Total synthesis of 0231B, an inhibitor of 3α-hydroxysteroid dehydrogenase produced by Streptomyces sp. HKI0231

The new inhibitors of 3α-hydroxysteroid dehydrogenase, 0231A 1 and 0231B 2, have a unique benz[c,d]indol-3(1H)-one structure in their molecules. In our advanced studies on indole chemistry, we have developed an efficient synthetic method for benz[c,d] ind
