Bm. Trost et al., A NOVEL CYCLOALKYLATION OF 1,6-ENYNES AND 1,7-ENYNES WITH STABILIZED PRONUCLEOPHILES, Tetrahedron letters, 35(9), 1994, pp. 1361-1364
Formation of five and six membered rings simultaneously with addition
of a functionalized side chain for further elaboration occurred upon e
xposing a 1:1 mixture of an enyne and a pronucleophile to a palladium
