摘要:The present invention relates to a process for the preparation of enantiomerically enriched cyclobutylamines of formula (I) from α-tertiary cyclobutanones and reacting said enantiomerically enriched cyclobutylamines to enantiomerically enriched cyclobutylamides. Such compounds are useful intermediates in the synthesis of microbiocidal thiazole compounds.

摘要:A process for producing a benzhydrol compound (II) which comprises hydrogenating a benzophenone compound (I) in the presence of a hydrogenation catalyst consisting of a transition metal complex, a base and an optically active diamine compound: (I) (II) wherein R1 to R10 each represents H, OH, C1-4 alkyl, C1-4 alkoxy, C1-4 alkanoyl, etc., R2 and R3, and R8 and R9 may form -CH=CH-CH=CH-, or any two of R1 to R9 adjacent to each other may be bonded to thereby form -OCH2O- or -(CH2)3-. By using this process, optically active benzhydrol compounds which have a high purity and are useful as, for example, intermediates in the synthesis of drugs can be produced by simple procedures.
