| titleOfInvention | A new type of diphenylmethane protective agent |
| abstract | The present invention is to develop a protective group that prevents the solidification or insolubilization of the functional group-protected compound and facilitates separation and purification after the reaction. The present invention provides a diphenylmethane compound, which is represented by the general formula (1) (in the formula, Y represents -OR 19 (here, R 19 represents a hydrogen atom or an active ester type protecting group), -NHR 20 (here, R 20 represents a hydrogen atom, a linear or branched alkyl group having 1 to 6 carbon atoms, or an aralkyl group, and at least one of R 1 to R 10 represents a group represented by formula (2), and the rest Represents a hydrogen atom, a halogen atom, an alkyl group having 1 to 4 carbon atoms, or an alkoxy group having 1 to 4 carbon atoms; R 11 represents a linear or branched alkylene group having 1 to 16 carbon atoms; X represents O or CONR 21 (here, R 21 represents a hydrogen atom or an alkyl group having 1 to 4 carbon atoms); A represents a group represented by formula (3) and the like). |
