2.3- epoxycyclohexanone 2-cyclohexenone

Ss2 reaction with a,fi-epoxy ketones.6 The enolate 1 of 2,3-epoxycyclohexanone reacts with methyllithium to give, after acidic work-up, 2-methy -2-cyclohexenone (3), the product of SN2 addition. Reaction of 1 with lithium dimethyl cuprate on the other hand results in 6-methyl-2-cyclohexcnonc (2), the product of Sv2 addition. [Pg.282]

Oxidations. Alcohols are oxidized in dichloroethane with catalytic amounts of a dichromate salt using sodium percarbonate as a recycling agent and PTC. - Epoxidations of enones by sodium perborate or NaOCP under PTC conditions give high yields. However, with NaOCl and hexaethylguanidinium chloride, cyclohexenones give 6,6-dichloro-2,3-epoxycyclohexanones. [Pg.266]

Epoxycyclohexanone of 20% ee was first prepared in 1980 by an enantioselecti-ve epoxidation of 2-cyclohexenone. However, enantiomerically pure 3-methyl- (34),... [Pg.163]
