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 streptomycinbiosynthesis in inactivemutants of Streptomycesgriseus.
