  Synthesis of Both Enantiomers of Four Different Macrocyclic Lactones

  摘要：

  Both enantiomers of macrocyclic lactones, 12-tridecanolide (1), 13-tetradecanolide (2), 14-pentadecanolide (3) and 15-hexadecanolide (4), were synthesized utilizing (S)-(-)-beta-hydroxythioacetal (5) as the chiral building block. Key steps are the C-alkylation of a dianion derived from 5 with alkyl dibromides followed by conversion of functional groups and the two macrolactonization. The both enantiomers of 1 similar to 4 have been obtained by reductive desulfurization of the dithiane moiety.
