1-nitro-2-propanol (1), in natural products syntheses was examined. Opticallypure (+)−1 was readily, prepared by the lipase-catalyzed stereoselective transesterification of (±)−1. The following Michael addition of TBDMS ether of (+)-1 to methyl vinyl ether or acrylonitrile afforded important synthetic intermediates, 3a and b. As a result, opticallypure sex pheromones for Bactrocera nigrotibialis
