Metabolism of rishitin. The NIH-like shift in formation of rishitin M-2
Abstract
Feeding experiments with (–)-[12,12-2H2]rishitin (1-D) in healthy potato tuber tissues indicated that metabolism of (1) into rishitin M-2 (3) proceeded with a stereospecific 1,2-migration of an olefinic hydrogen at C-12 of (1) in contrast with formation of rishitin M-1 (2) by direct oxygenation on C-13 of (1).
