An enantiocontrolled synthesis of (–)-malyngolide
Abstract
Enantioselective synthesis of (–)-malyngolide (1) was accomplished by employing diastereo-selective addition of nonylmagnesium bromide to the 2-acylfuran derivative (4), followed by a ring transformation of the resulting optically active 2-furylalcohol (5) to give the pyranone derivative (7) as key steps.
