| abstract |
NEW MATERIAL:The compound of formula I or II [R 1 to R 3 are 1-10C alkyl; R 4 and R 5 are 1-10C (substituted) alkyl or (substituted) phenyl and are different from each other] having silyl group at γ-site. n EXAMPLE: The epoxy alcohol of formula III. n USE: A synthetic intermediate for pharmaceuticals and agricultural chemicals such as prostaglandin. n PREPARATION: An epoxyketone compound having silyl group at γ-site and expressed by formula IV or V is made to react with preferably 0.8-1.5 equivalent of an organic magnesium reagent of formula R 5 MgX (x is Cl, Br or I) (e.g. CH 3 MgI or C 2 H 5 MgBr) at -78 to 0°C for 0.5-5hr. n COPYRIGHT: (C)1991,JPO&Japio |
