Asymmetric Reactions of Axially Chiral Amides: Use of Removable ortho-Subin Radical Cyclizations of o-Iodoacrylanilides and N-Allyl-N-o-iodo50- 076 stituents
acrylamides. — Axially chiral o-iodoacrylanilides and N-allyl-N-o-iodoacrylanilides
bearing an ortho Br or Tms substituent efficiently undergo regio- and stereoselective
cyclization. These substituents can easily be removed or replaced, thus allowing a convenient synthesis of a number of optically active indole derivatives present in natural
products (to be continued). — (PETIT, M.; GEIB, S. J.; CURRAN*, D. P.;
