Dihydro- and Tetrahydrofuran Building Blocks from 1,4:3,6-Dianhydrohexitols. 2. Synthesis of Acetal, Alcohol, Diol, Epoxide, Hydrocarbon, and Lactone Pheromones
摘要:
The potential of building blocks 1-3 for synthesis of enantiopure substances is illustrated by their transformation to various insect pheromones featuring functionalities specified in the title. A convenient synthesis of building block 3 from sorbitol is described.
Both enantiomers of a series of delta-lactones (e.g., delta-decalactone, delta-dodelactone, and delta-hexadecalactone) were synthesized stereoselectively by Novozym 435-catalyzed resolution. Furthermore, only (S)-enantiomers of delta-lactones were synthesized with a combination of Novozym 435-catalyzed resolution and Mitsunobu reaction.

Optical resolution of(±)-2-chloroacetylaminotridecanoic acid with amino acylase gave (S)-2-aminotridecanoic add, which was converted into highly optically pure (S)-5-hexadecanolide (the pheromone of Vespa orientalls). Similarly (R)-2-chloroacetylammotridecanoic acid recovered after the enzymic hydrolysis yielded (R)-5-hexadecanolide. The existing methods for the preparation of the enantiomers of 5-hexadecanolide
