Preparation of isopropylidene acetals from butane-1,2,4-triol and its cyclopropane congeners

Features of isopropylidene acetal synthesis from butane-1,2,4-triol and its cyclopropane congeners were studied. Procedures for the preparation and purification of the respective acetonides have been developed.
