Abstract

(&)-Podorhizol and (f)-Isopodophyllotoxone J, Org. Chem., Vol. 43, No. 5, 1978 985 considerably lower than in the undeuterated material. The carbonyl band was unchanged (1710 cm-') while other significant bands fell at 1600, 1460, 1425, 1363, 1340, 1222, 1122, and 837 cm-*.(See text for a discussion of the IVMR spectrum.) The mass spectrum gave parent ion mie 304 and indicated the absence@ any oxidative product or material that ...
