PREPARATION OF OPTICALLY ACTIVE HYDRAZINES AND AMINES

摘要

2131792 9319040 PCTABS00025 A process for the asymmetric hydrogenation of N-acylhydrazones to optically active N-acylhydrazines in the presence of a chiral phospholane catalyst complex, a process for the reductive N-N bond cleavage of N-acylhydrazine to amines with samarium diiodide, and a multistep process for converting keto group-bearing compounds to the corresponding optically active amino group-bearing compounds are disclosed.
