[GRAPHICS]A convergent asymmetric synthesis of (-)-ratjadone (1) has been achieved, confirming the assignments of stereochemistry for the naturally occurring antifungal metabolite.
Ratjadone is an antifungal and highly cytotoxic polyketide from Sorangium cellulosum. The tetrahydropyran ring is supposed to result from an intramolecular opening of a C16-C17 epoxide. Herein we report the biomimetic synthesis of the C15-C24 segment of ratjadone. (C) 1999 Elsevier Science Ltd. Ali rights reserved.
