Page/Page column 5, (2012/11/08)
A method for manufacturing an acetal compound represented by the formula [1] in which the steps (A) to (D) as defined herein are performed sequentially, and an acetal compound of the formula [1] which is produced by the method: wherein n is 0 or 1 provided that R1 groups may be bonded or may not be bonded to each other when n is 0; R1 is an alkyl group having 1 or 2 carbon atoms or an alkylene group having 1 or 2 carbon atoms and the R1 groups may be same or different from each other; and R2 is an alkylene group having 1 or 6 carbon atoms.

A convergent strategy was elaborated to synthesize maytansine 1 and maytansinoids modified on the carbon skeleton, especially 4-demethylmaytansine 2, 6-demethylmaytansine 3, 4,6-bisdemethylmaytansine 4.In this paper, the feasibility of the project was verified by the preparation of key intermediates for the synthesis of 4,6-bisdemethylmaytansine and 6-demethylmaytansine.The C-1-N open chain compound 18 in the 4,6-bisdemethyl series was obtained.
