Replication of biosynthetic reactions enables efficient synthesis of A-factor, a γ-butyrolactone autoinducer from Streptomyces griseus

We report a concise synthesis of A-factor, the prototypical γ-butyrolactone signalling compound of Streptomyces bacteria. In analogy to enzymatic reactions in A-factor biosynthesis, our synthesis features a tandem esterification-Knoevenagel condensation yielding a 2-acyl butenolide and a surprising, chemoselective conjugate reduction of this α,β- unsaturated carbonyl compound using sodium cyanoborohydride.

Regioselective synthesis of hydroxy butenolides: A convenient synthesis of A-factor

An elegant approach for the regioselective preparation of hydroxy butenolide by the oxidation of 2-ethoxyfuran with MnO2-HCl is described.

A Synthesis of 3-Hydroxymethyl-2-(6-methylheptanoyl)-4-butanolide (A-Factor)

The A-Factor was conveniently synthesized from 3-furoic acid via the Birch reduction.

SYNTHESIS OF OPTICALLY ACTIVE FORMS OF A-FACTOR, THE INDUCER OF STREPTOMYCIN BIOSYNTHESIS IN INACTIVE MUTANTS OF STREPTOMYCES GRISEUS

The absolute configuration at C-3 of A-factor, 2-(6-methylheptanoyl)-3-hydroxymethyl-4-butanolide 1a, was determined to be S by synthesizing both enantiomers of it from paraconic acid. (3S)-A-factor was 2.5 times more active than the (3R)-isomer as the inducer of streptomycin biosynthesis in inactive mutants of Streptomyces griseus.
