Modular Stereodivergent Chemoenzymatic Total Synthesis of (+)‐ and (‐)‐ <i>Glabridin</i>

Herein, we describe a modular, stereodivergent chemoenzymatic strategy for the enantioselective total synthesis of the natural products (+)- and (-)-glabridin. A lipase-catalyzed dynamic kinetic resolution establishes the key benzylic stereocenter, while a carefully engineered protecting-group manifold preserves stereochemical integrity during fragment coupling and cyclization. From inexpensive, commercially available resorcinol-derived building blocks, the sequences deliver (-)-glabridin in 10 steps with 14% overall yield and (+)-glabridin in 12 steps with 7% overall yield. This convergent platform provides practical access to both enantiomers of glabridin and offers a general blueprint for the stereocontrolled synthesis of structurally related polyphenolic natural products.

Abstract

Herein, we describe a modular, stereodivergent chemoenzymatic strategy for the enantioselective total synthesis of the natural products (+)- and (-)-glabridin. A lipase-catalyzed dynamic kinetic resolution establishes the key benzylic stereocenter, while a carefully engineered protecting-group manifold preserves stereochemical integrity during fragment coupling and cyclization. From inexpensive, commercially available resorcinol-derived building blocks, the sequences deliver (-)-glabridin in 10 steps with 14% overall yield and (+)-glabridin in 12 steps with 7% overall yield. This convergent platform provides practical access to both enantiomers of glabridin and offers a general blueprint for the stereocontrolled synthesis of structurally related polyphenolic natural products.
