Definitions
- the present invention relates to a novel benzyl compound useful as a protective agent for functional groups such as a carboxy group, a hydroxyl group, a diol group, an amino group, and a mercapto group.
- an object of the present invention is to provide a protecting group that facilitates separation and purification after the reaction without solidification or insolubilization by improving the solubility of the functional group-protected compound in an organic solvent. It is in.
- the present inventor has found that a compound in which a functional group is protected using a compound having a trialkylsilyloxy group via an oxyalkylene group on the benzene ring.
- the present invention was completed by discovering that the compound is difficult to precipitate and can be easily separated and purified by liquid-liquid phase separation, and that the compound is useful as a protective agent.
- the present invention provides the following [1] to [5].
- X 1 is —CH 2 OR 14 (wherein R 14 represents a hydrogen atom, a halogenocarbonyl group or an active ester-type protecting group), —CH 2 NHR 15 (where R 15 is a hydrogen atom, A linear or branched alkyl group having 1 to 6 carbon atoms or an aralkyl group), a halogenomethyl group, a methyl azide group, a formyl group or an oxime; At least one of R 1 , R 2 , R 3 , R 4 and R 5 has the formula (2)
- R 6 represents a linear or branched alkylene group having 1 to 16 carbon atoms
- X 2 represents O or CONR 16 (where R 16 represents a hydrogen atom or an alkyl group having 1 to 4 carbon atoms)
- A is the formula (3), (4), (5), (6), (7), (8), (9), (10), (11), (12) or (13)
- R 7 , R 8 and R 9 are the same or different and each represents a linear or branched alkyl group having 1 to 6 carbon atoms, or an aryl group which may have a substituent;
- R 10 represents a single bond or a linear or branched alkylene group having 1 to 3 carbon atoms, and R 11 , R 12 and R 13 each represents a linear or branched alkylene group having 1 to 3 carbon atoms
- X 1 is —CH 2 OR 14 (where R 14 represents a hydrogen atom, a halogenocarbonyl group or an active ester-type protecting group), —CH 2 NHR 15 (where R 15 is a hydrogen atom, carbon
- the benzyl compound according to [1] which is a linear or branched alkyl group of 1 to 6 or an aralkyl group), or a halogenomethyl group.
- a compound having a functional group protected with the benzyl compound (1) of the present invention is liable to be liquid and has improved solubility in a solvent. Therefore, separation after a condensation reaction can be performed by an operation such as liquid-liquid phase separation. Easy to purify. In addition, the protecting group can be easily removed. In the manufacturing process of various chemical substances such as pharmaceuticals and agricultural chemicals, when insolubilization and solidification of raw materials and intermediates are hindered, these can be achieved by binding the benzyl compound (1) of the present invention to the raw materials and intermediate compounds.
- the benzyl compound of the present invention represented by the general formula (1) is characterized in that at least one of R 1 to R 5 has the structure of the formula (2).
- the compound in which the functional group is protected using the benzyl compound (1) of the present invention tends to be liquid, and the solubility in a solvent is remarkably improved.
- X 1 is —CH 2 OR 14 (where R 14 represents a hydrogen atom, a halogenocarbonyl group or an active ester-type protecting group), —CH 2 NHR 15 (where R 15 Represents a hydrogen atom, a linear or branched alkyl group having 1 to 6 carbon atoms, or an aralkyl group), a halogenomethyl group, a methyl azide group, a formyl group, or an oxime.
- examples of the halogen atom include a fluorine atom, a bromine atom, a chlorine atom, and an iodine atom.
- Examples of the active ester type protecting group include an active ester type carbonyl group and an active ester type sulfonyl group.
- Examples of the active ester type carbonyl group include a carbonyloxysuccinimide, an alkoxycarbonyl group, an aryloxycarbonyl group, an aralkyloxycarbonyl group, and the like, more preferably a carbonyloxysuccinimide.
- Examples of the active ester type sulfonyl group include an alkylsulfonyl group and an arylsulfonyl group, and more preferable examples include a C 1 -C 6 alkylsulfonyl group and a p-toluenesulfonyl group.
