C. Gravierpelletier et al., ENANTIOPURE HYDROXYLACTONES FROM L-ASCORBIC AND D-ISOASCORBIC ACIDS .2. SYNTHESIS OF (-)-(5R, 6S)-6-ACETOXY-5-HEXADECANOLIDE AND ITS DIASTEREOMERS, Tetrahedron, 51(6), 1995, pp. 1663-1674
Strategies to enantiopure 6-hydroxy-delta-valerolactones, through bis-
epoxide formal equivalents issued from L-ascorbic and D-isoascorbic ac
ids, are studied. The approaches notably involve Mitsunobu reaction on
diols or triols and opening of the resulting epoxides.
