title: Nmr studies of colchicine and its photoisomers, beta- and gamma-lumicolchicines.
abstract: Unambiguous 1H- and 13C-nmr assignments of colchicine, beta-lumicolchicine, and gamma-lumicolchicine have been obtained using a combination of 1D- and 2D-nmr spectroscopic techniques. The data indicate that gamma-lumicolchicine is a stereoisomer of beta-lumicolchicine and provide definitive evidence for their stereochemical assignments.
