We describe a novel and convenient method for quinoline synthesis using ring-closing olefin metathesis (RCM), ene-ene metathesis, and ene-enol ether metathesis. We also report the first example of enol silyl ether-ene metathesis to produce cyclic enol silyl ether. Using this method, versatile substituted quinoline derivatives were readily prepared in excellent yield from anthranilic acid derivatives. C 2001 Elsevier Science Ltd. All rights reserved.
