Achiral as well as chiral 2,3-olefinic acetals are converted into 2- and 3- hydroxy acetals via LAH reduction of the corresponding epoxides and via bromohydrins followed by TBTH reductions respectively. Synthesis of 1,3-diones is described. Compounds from chiral systems are further utilized for asymmetric synthesis.
