Definitions and general terms
Reference will now be made in detail to certain embodiments of the invention, examples of which are illustrated by the accompanying structural and chemical formulas. The invention is intended to cover alternatives, modifications and equivalents, which may be included within the scope of the invention as defined by the appended claims. One skilled in the art will recognize that many methods and materials similar or equivalent to those described herein can be used in the practice of the present invention. The present invention is in no way limited to the methods and materials described herein. In the event that one or more of the incorporated documents, patents, and similar materials differ or contradict this application (including but not limited to defined terminology, application of terminology, described techniques, and the like), this application controls.
It will be further appreciated that certain features of the invention, which are, for clarity, described in the context of separate embodiments, may also be provided in combination in a single embodiment. Conversely, various features of the invention which are, for brevity, described in the context of a single embodiment, may also be provided separately or in any suitable subcombination.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. All patents and publications referred to herein are incorporated by reference in their entirety.
The following definitions, as used herein, should be applied unless otherwise indicated. For the purposes of the present invention, the chemical elements are in accordance with the CAS version of the periodic Table of the elements, and the handbook of chemistry and Physics, 75 th edition, 1994. In addition, general principles of Organic Chemistry can be referred to as described in "Organic Chemistry", Thomas Sorrell, University Science Books, Sausaltito: 1999, and "March's Advanced Organic Chemistry" by Michael B.Smith and Jerry March, John Wiley & Sons, New York:2007, the entire contents of which are incorporated herein by reference.
The articles "a," "an," and "the" as used herein are intended to include "at least one" or "one or more" unless otherwise indicated or clearly contradicted by context. Thus, as used herein, the articles refer to one or to more than one (i.e., to at least one) of the objects. For example, "a component" refers to one or more components, i.e., there may be more than one component contemplated for use or use in embodiments of the described embodiments.
The term "comprising" is open-ended, i.e. includes the elements indicated in the present invention, but does not exclude other elements.
The term "stereoisomers" refers to compounds having the same chemical structure, but differing in the arrangement of atoms or groups in space. Stereoisomers include enantiomers, diastereomers, conformers (rotamers), geometric isomers (cis/trans), atropisomers, and the like.
"enantiomer" refers to two isomers of a compound that are not overlapping but are in mirror image relationship to each other.
"diastereomer" refers to a stereoisomer that has two or more chiral neutrals and whose molecules are not mirror images of each other. Diastereomers have different physical properties, such as melting points, boiling points, spectral properties, and reactivities. Mixtures of diastereomers may be separated by high resolution analytical procedures such as electrophoresis and chromatography, e.g., HPLC.
The stereochemical definitions and rules used in the present invention generally follow the general definitions of S.P. Parker, Ed., McGraw-Hill Dictionary of Chemical Terms (1984) McGraw-Hill Book Company, New York; and Eliel, E.and Wilen, S., "Stereochemistry of Organic Compounds", John Wiley & Sons, Inc., New York, 1994.
Many organic compounds exist in an optically active form, i.e., they have the ability to rotate the plane of plane polarized light. In describing optically active compounds, the prefixes D and L or R and S are used to denote the absolute configuration of a molecule with respect to one or more of its chiral centers. The prefixes d and l or (+) and (-) are the symbols used to specify the rotation of plane polarized light by the compound, where (-) or l indicates that the compound is left-handed. Compounds prefixed with (+) or d are dextrorotatory. A particular stereoisomer is an enantiomer and a mixture of such isomers is referred to as an enantiomeric mixture. A50: 50 mixture of enantiomers is referred to as a racemic mixture or racemate, which may occur when there is no stereoselectivity or stereospecificity in the chemical reaction or process.
Any asymmetric atom (e.g., carbon, etc.) of a compound disclosed herein can exist in racemic or enantiomerically enriched forms, such as the (R) -, (S) -or (R, S) -configuration. In certain embodiments, each asymmetric atom has at least 50% enantiomeric excess, at least 60% enantiomeric excess, at least 70% enantiomeric excess, at least 80% enantiomeric excess, at least 90% enantiomeric excess, at least 95% enantiomeric excess, or at least 99% enantiomeric excess in the (R) -or (S) -configuration.
Depending on the choice of starting materials and methods, the compounds of the invention may exist as one of the possible isomers or as mixtures thereof, for example as racemates and mixtures of non-corresponding isomers (depending on the number of asymmetric carbon atoms). Optically active (R) -or (S) -isomers can be prepared using chiral synthons or chiral reagents, or resolved using conventional techniques. If the compound contains a double bond, the substituents may be in the E or Z configuration; if the compound contains a disubstituted cycloalkyl group, the substituents of the cycloalkyl group may have cis or trans configuration.
Any resulting mixture of stereoisomers may be separated into pure or substantially pure geometric isomers, enantiomers, diastereomers, depending on differences in the physicochemical properties of the components, for example, by chromatography and/or fractional crystallization.
The racemates of any of the resulting end products or intermediates can be resolved into the optical enantiomers by known methods using methods familiar to those skilled in the art, e.g., by separation of the diastereomeric salts obtained. The racemic product can also be separated by chiral chromatography, e.g., High Performance Liquid Chromatography (HPLC) using a chiral adsorbent. In particular, enantiomers can be prepared by asymmetric synthesis.
In addition, unless otherwise explicitly indicated, the descriptions of the terms "… independently" and "… independently" and "… independently" used in the present invention are interchangeable and should be understood in a broad sense to mean that the specific items expressed between the same symbols do not affect each other in different groups or that the specific items expressed between the same symbols in the same groups do not affect each other.
