The reaction of O-deprotoneted N-phenylhydroxylamines 1 with various electron-deficient allenes 2, 14, 16 gives, via Michael addition and Cope-rearrangement, substituted anilines 5, which are easily convertible into indoles 6.In this manner, sulfoxides 17
HETERO-COPEUMLAGERUNGEN-II. EINFACHE UND FLEXIBLE SYNTHESEN FUER 2-SUBSTITUIERTE INDOLE
Blechert, Sigfried
, p. 1547 - 1550 (2007/10/02)
The reaction of N-phenylhydroxylamine derivatives with electron withdrawing allenes gives o-alkylated anilines, which can further react to form 1,2-disubstituted indoles. 2-Substitu ed indoles are directly obtainable from reaction with N-phenyl-nitrones.
