Pheromone Synthesis; CXXXIX.1Enzymatic Preparation of (2S,3R)-4-Acetoxy-2,3-epoxybutan-1-ol and Its Conversion to the Epoxy Pheromones of the Gypsy Moth and the Ruby Tiger Moth

All articles of this category Pig pancreatic lipase-catalyzed asymmetric hydrolysis of 1, 4-diacet-oxy- cis -2,3-epoxybutane yielded (2 S ,3 R ) -4-acetoxy-2,3-epoxybu-tan-1-ol, which was converted to two naturally occurring epoxides: the gypsy moth pheromone, disparlure [(7 R ,8 S )-7,8-epoxy-2-methyloctadecane] and the ruby tiger moth pheromone [(6 Z ,9 S ,10 R ) -9,10-epoxy-6-henicosene].
