Straightforward, metal-free, and stereoselective synthesis of 9-oxo- and 10-hydroxy-2(E)-decenoic acids, important components of honeybee (Apis mellifera) secretions†
Abstract
10-Hydroxy-2E-decenoic (10-HDA) and 9-oxo-2E-decenoic (9-ODA) acids, two components identified in honeybee secretions, have both received considerable recent interest due to their involvement in caste switch and maintenance. Herein we report for the first time a metal-free, gram scale, and stereoselective synthesis of these honeybee secretion components by TEMPO catalyzed
