Abstract Irradiation of 17-keto-estranes bearing an 11-aryl substituent offers a preparatively useful access to pharmacologically interesting steroids with inverted configuration at C-13.
Tetrahedron Letters | 1980
Günter Neef; Ulrich Eder; Arne Seeger
Abstract Nucleophilic attack of methyllithium on allene sulfoxides offers a stereospecific access to sulfur-free allenes. Reaction of phenylsulfinyl substituted diene 15 leads via a benzilic-type rearrangement to phenyl substituted diene 18 .

Ethyl β-carboline-3-carboxylate (1a) and its 4-alkyl derivatives (1b–d) are hydroxylated by Sporotrichum sulfurescens at C-6 and C-8 of the aromatic nucleus; side chain hydroxylation of (1c) and (1d) occurs with Streptomyces lavendulae and Streptomyces griseus.
