A Carbonyl Ylide Cycloaddition Approach to Platensimycin

Abstract

Short and to the point: A formal synthesis of platensimycin has been accomplished by employing a carbonyl ylide [3+2] cycloaddition reaction (see scheme). This short and facile enantioselective synthesis of the pivotal tetracyclic precursor requires 11 steps and proceeds in 20 % overall yield from isopropyl cyanoacetate.
