Subjects
*RHODIUM catalysts, *PLATINUM group catalysts, *NITRONES
Abstract

N-Phenyl-α-arylnitrones react with symmetrical dialkylacetylenes to form unsymmetrically 2,3-diaryl-substituted N-unprotected indole derivatives in moderate to often high yields. The scalable, regioselective reaction is applicable to dialkylacetylenes and tolerates diverse functional groups. [ABSTRACT FROM AUTHOR]
