Hydrolytic kinetic resolution of terminal mono- and bis-epoxides in the synthesis of insect pheromones: routes to (−)-( R )- and (+)-( S )-10-methyldodecyl acetate, (−)-( R )-10-methyl-2-tridecanone, (−)-( R )-( Z )-undec-6-en-2-ol (Nostrenol), (−)-(1 R ,7 R )-1,7-dimethylnonyl propanoate, (−)-(6 R ,12 R )-6,12-dimethylpentadecan-2-one, (−)-(2 S ,11 S )-2,11-diacetoxytridecane and (+)-(2 S ,12 S )-2,12-diacetoxytridecane

enantiomerically enriched epoxides and diols, which have been transformed into important insect sex pheromones. In this general approach, (−)-(R)- and (+)-(S)-10-methyldodecyl acetates from the smaller tea tortrix moth were obtained, as was (−)-(R)-10-methyltridecan-2-one from the southern corn rootworm. The (S)-epoxide obtained from undec-1-en-6-yne was transformed to (−)-(R)-(Z)-undec-6-en-2-ol (Nostrenol)
使用(salen)Co(OAc)配合物的官能化环氧化物的水解动力学拆分(HKR)提供了对映体富集的环氧化物和二醇,它们已转化为重要的昆虫性信息素。在这种通用方法中,从较小的茶to蛾中获得了(-)-(R)-和(+)-(S)-10-甲基十二烷基乙酸酯,以及(-)-(R)-10-甲基叔丁基酚2 -来自南部玉米根虫的一种。从十一烯-1-烯-6-炔获得的(S)-环氧化物从蚁狮转变为(-)-(R)-(Z)-十一烯-6-烯-2-醇(Nostrenol)。还研究了合适的双环氧化物的HKR,并提供了生成的双环氧化物和环氧二醇的转化(-)-(1 R,7 - [R )从玉米根-1,7- dimethylnonylpropanoate,( - ) - (6 - [R,12 - [R)-6,12-dimethylpentadecan -2-酮从阴带状黄瓜甲虫,和( - ) - (2-小号来自雌豌豆mid的,11 S
