A process for preparing a substituted alkene diol, of the formula (I) wherein n is 0 to 4, R is an unsubstituted or substituted aliphatic or aromatic radical, R1 is hydrogen or an aliphatic or aromatic radical and each of R?2, R3, R4 and R5¿ which are the same or different, is hydrogen or an unsubstituted or substituted aliphatic or aromatic radical, or R?2 and R3¿ together form a divalent radical having 1 to 4 chain carbon atoms which comprises reacting an epoxide of the formula (II) wherein n, R?1, R2, R3, R4 and R5¿ are as defined above with an organolithium compound of the formula: RLi wherein R is as defined above is described. Some of the starting materials and final products are novel.
