The alkylation of dibutylstannylene derivatives of 1,2-O-isopropylidene-myo-inositol

Gigg,Gigg,Martin-Zamora

, p. 2827 - 2830 (2007/10/02)

Benzylation (or allylation) of 1,2-O-isopropylidene-myo-inositol in the presence of an excess of dibutyltin oxide gives, as major products, the readily isolable 3,4,6- (12) and 3,5,6-tri-O-alkyl (13) derivatives which are valuable intermediates for the synthesis of inositol phosphates of the phosphates of the phosphatidylinositol cycle.
