    摘要: The present invention provides compounds and methods that can be used to convert the intermmediate halomethyl ketones (HMKs), e.g ., chloromethyl ketones, to the corresponding S,S- and R,S- diastereomers. More particularly, the present invention provides: (1) reduction methods; (2) inversion methods; and (3) methods involving the epoxidation of alkenes. Using the various methods of the present invention, the R,S-epoxide and the intermediary compounds can be prepared reliably, in high yields and in high purity.
