I. Bhattacharya et al., A CONVENIENT SYNTHESIS OF VINYL EPOXIDES FROM GLYCIDIC ESTERS VIA ALPHA-HYDROXY-BETA,GAMMA-UNSATURATED ESTERS, Synthetic communications, 23(17), 1993, pp. 2405-2414
Glycidic esters, upon isomerisation with BF3.Et2O yield alpha-hydroxy-
beta, gamma-unsaturated esters. These arg then reduced with LiAlH4 to
vicinal diols which are converted to vinyl epoxides in two steps.
