The Stereoselective Synthesis of Tobacco Beetle Pheromone-(7S)-(-)-4,6-dimethyl-7-hydroxyl-3-nonanone
Abstract:
Using an available compound 3-pentanone(1) as starting material, the key intermediate compound 4,6-dimethyl-3,7-nonandione(5) was synthesized through the additionelimination of silylenol ether and Michael addition of T-methylene 3-pentanone(4) with silylenol ether(2). In the presence of chiral reagent 6U-phenyl amino-3U,5T-chlorestandiol(7), compound (5) was reduced by KBH4 directly to give Tobacco Beetle Pheromone (7S)-(-)-4,6-dimethyl-7-hydroxyl-3-nonanone(6). [T]D25=-35.87°(c=0.23, CHCl3), overall yield 23.9%.
