Abstract
Compounds having bi-cyclic structure comprising a partially unsaturated 6-carbon first cyclic moiety interconnected to a 6-carbon second cyclic moiety second via a divalent linking moiety are provided. The compounds can be used as intermediates compounds in methods for the synthesis of carbazoles and derviatives thereof, including carvedilol, and tricyclic alkylhydroxamates, which do not require Fischer indole synthetic steps. Methods of preparing the compounds having bi-cyclic structures are also provided.
