Synthesis of substituted 1,2-dihydroquinolines and quinolines using ene-ene metathesis and ene-enol ether metathesis

Arisawa, Mitsuhiro,Theeraladanon, Chumpol,Nishida, Atsushi,Nakagawa, Masako

, p. 8029 - 8033 (2001)

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.
