Asymmetric synthesis of (S)-(-)-N-acetylcolchinol via Ullmann biaryl coupling

A modified Ziegler Ullmann coupling process has been developed as the key step in an effective synthesis of (S)-(-)-N-acetylcolchinol, analogues of which are selective vascular targeting agents with potential importance in cancer chemotherapy. Asymmetric induction is achieved by enamide hydrogenation using FerroTANE catalysts.

Synthesis of (-)-Steganone

A novel, highly efficient route to the key steganone intermediate 2,3,4-trimethoxy-6,7-methylenedioxy-9-(pyrrolidin-1-yl)phenanthrene (8) is described.Resolution of the derived 5,6,7,8-tetrahydro-1,2,3-trimethoxy-10,11-methylenedioxy-8-oxodibenzocycl
