Abstract

Abstract (1) 1, 5-Dienes are readily prepared by titanium mediated methylenation of allyl esters, Claisen rearragement followed by a second methylene transfer reaction.(2) The same 1, 5-diene may be approached in “one pot” combining an allyl acetate and 3 equivalents biscyclopentadienyl-titanium-μ-methylidene-bismethyl aluminum.
