Tandem chain extension–iodomethylation reactions: formation of α-functionalized γ-keto carbonyls
摘要:
Sequential exposure of a zinc-organometallic intermediate, generated through a zinc carbenoid-mediated chain extension reaction of a beta-keto carbonyl, to trimethylsilylchloride and iodine provided regioselective formation of an alpha-iodomethyl-gamma-keto carbonyl. The iodomethyl functionality can be further manipulated to provide side chains that are potential mimics of a-amino acid side chains. (C) 2008 Elsevier Ltd. All rights reserved.
