Reaction of organolithiums with fluoro-N,N-diallylanilines: A benzyne-mediated anionic cascade leading to 3,4-disubstituted indolines
Bailey, William F.,Carson, Matthew W.
, p. 1329 - 1332 (1997)
Regioselective ortho-lithiation of either 2-fluoro- (2) or 3-fluoro-N,N-diallylaniline (3) initiates an anionic cascade leading to an N-allyl-3,4-disubstituted indoline. The transformation involves loss of LiF from the ortho-lithiated species, regioselective intermolecular addition of the organolithium to the benzyne intermediate, and cyclization of the resulting [6-substituted-2-(N,N-diallylamino)phenyl]lithium.
New method for the preparation of an active manganese species and its use for radical cyclization reactions
Tang, Jun,Shinokubo, Hiroshi,Oshima, Koichiro

Reduction of Li2MnCl4 with magnesium in THF afforded a fairly active manganese species which readily initiated radical cyclization of 2-iodoethanal allylic acetals at room temperature. The corresponding 2-bromoethanal acetals also pr
