Description
Technical Field
The invention relates to the technical field of molecular synthesis of drug intermediates and organic chiral building blocks, and particularly discloses a preparation method of chiral beta-alkylamide compounds.
Background
Chiral C (sp3) -C (sp3) Bonds are widely present in natural products and drugs with biological activity, chiral C (sp3) -C (sp3) The construction of bonds has been a focus of research on organic synthesis. The enantioselective cross coupling reaction catalyzed by transition metal is efficient synthesis of chiral C (sp3) -C (sp3) One of the methods of bonding compounds, the limitation of which is the preparation and use of organometallic reagents. Another construction chiral C (sp3) -C (sp3) The bond is formed by asymmetric hydroalkylation of olefins, which is a major difficulty in the regioselectivity of the reaction from olefins via metal hydrogen species reactions to produce hydroalkylated products. The metal catalyzed reductive coupling reaction is an important method for constructing carbon-carbon bonds, and the reaction directly uses electrophiles for coupling, so that the preparation and the use of metal reagents are avoided, and the metal-catalyzed reductive coupling reaction is widely developed in recent years. Wherein an asymmetric reductive coupling reaction using a secondary electrophile can efficiently synthesize a series of chiral compounds, but the asymmetric reductive coupling reaction is mainly focused on the construction of chiral C (sp2) -C (sp3) Bond, so far metal catalytic reduction coupling reaction constructs chiral C (sp3) -C (sp3) Bonds have not been reported.
The main challenge of the asymmetric reduction coupling reaction of two molecules of alkyl electrophiles catalyzed by metal is the control of the reaction selectivity and chirality. Due to the similarity of raw materials and the high reactivity of alkyl electrophiles, a large number of self-coupling side reactions occur in the reaction, resulting in reduced selectivity of cross coupling, and chiral control of alkyl metal alkyl species is also a great difficulty. The present invention provides an efficient method for achieving this conversion process.
Chiral beta-alkylamides are an important class of organic synthons that contain such chiral backbones in many natural products as well as biological inhibitors. In the prior art, few synthesis methods of chiral beta-alkylamide compounds are reported, so that development of an effective synthesis route of chiral beta-alkylamide compounds with high stereoselectivity is urgently needed.

The resulting mixture of any stereoisomers may be separated into pure or substantially pure geometric isomers, enantiomers, diastereomers, e.g., by chromatography and/or fractional crystallization, depending on the differences in the physicochemical properties of the components.
Any of the resulting racemates of the end products or intermediates can be resolved into the optical enantiomers by known methods, such as,by separating the diastereoisomeric salts thereof obtained.
