An unprecedented asymmetric acyl-carbamoylation of pendant alkenes tethered on aryl carbamic chlorides with both aliphatic and aromatic aldehydes has been developed via the cooperative catalysis of a chiral nickel-PHOX complex and tetrabutylammonium decatungstate. This reaction represents the first example of merging hydrogen-atom-transfer photochemistry and asymmetric transition metal catalysis in difunctionalization of alkenes. Using this protocol, a variety of oxindoles bearing a challenging quaternary stereogenic center are furnished under mild conditions in highly enantioselective manner.

A series of 2-diphenylphosphinoyl-3-hydroxy, amino and alkyl indole derivatives have been efficiently prepared by base-induced intramolecular cyclization of aromatic Horner-Wittig reagents containing carboxamido, cyano and oxo groups, respectively.
An Expeditious Synthesis of 3-Alkyl-, Aryl- and Heteroaryl-indoles by way of an Intramolecular Horner-Wittig Reaction

, p. 2463 - 2466 (2007/10/02)
A variety of 3-alkyl-, aryl- and heteroaryl-indoles have been efficiently prepared by base-induced intramolecular cyclization of suitable aromatic o-acyl substituted Horner-Wittig reagents.
