(-)-Padocin: A novel epoxylignan from Haplophyllum cappadocicum

Haplophyllum cappadocicum (Rutaceae) of Turkish origin yielded a novel lignan, incorporating an unusual 6,9' fusion in a 9,9'-epoxylignan structure. Extensive 2D nmr experiments and catalytic hydrogenolysis are undertaken for the elucidation of structure with the relative configuration given in 1. © 1994.
