Abstract :
A convergent enantioselective synthesis of penicimarin B, aspergillumarin A and B has been reported using Brown’s allylation, DeBrabander–Bhattacharjee lactonization and Grubbs cross coupling metathesis. During this synthesis we have standardized the conditions for DeBrabande–Bhattacharjee lactonization to obtain excellent yield (>90%).
