Abstract

A practical synthesis of CBI (2), utilizing inexpensive starting materials, waa developed and applied to the synthesis of benzannelated analogs of CC-1065, in particular CBI-PDE-I- dimer (13) and CBI-bis-indole (17). While a Sharplea asymmetric dihydroxylation reaction proved effective at providing optically active intermediates, a more classical resolution procedure waa used to prepare materials of higher optical purity. A novel cyclization ...
