Abstract
Optically active A‐factor (1), the factor from Streptomyces viridochromogenes (2), the factors from S. bikiniensis and S. cyaneofuscatus (3–5), and virginiae butanolides A (6), B (7), C (8), and D (9) were synthesized starting from (S)‐(−)‐paraconic acid (10). The absolute configurations of virginiae butanolides A and C were deduced to be (2__S__,3__R__,1′R).
