摘要

Various camphor derived N- and O-enones were treated with selected oxidants to provide the corresponding epoxides in a wide range of diastereoselectivity. For camphorsultam derived activated alkenes, high to excellent stereoselectivities were obtained when the s-trans enones were treated with methyl(trifluoromethyl)dioxirane. On the other hand, for exo-10,10-diphenyl-2, 10-camphanediol (3) and exo-10,10-diphenyl-10-methoxy-2-camphanol (4) derived alkenes, the use of s-cis enones gave the desired epoxide with excellent diastereoselectivity under the same reaction conditions. The stereoselectivity was highly dependent on the geometry of the auxiliaries derived enones and the stereochemical induction is discussed.
