Mr. Seong et al., THE REACTION OF ORGANOMETALLIC COMPOUNDS WITH THE WEINREB AMIDE OF 3,7-DICHLOROQUINOLINE-8-CARBOXYLIC ACID, Synthetic communications, 28(1), 1998, pp. 139-145
The reaction of Grignard or organolithium reagents with the Weinreb am
ide of 3,7-dichloroquinoline-8-carboxylic acid afforded 2-substituted
derivatives 5 via nucleophilic substitution reaction with hydride tran
sfer as the major product instead of the normally expected ketone deri
vatives 4.
