Cyclobutene formation accompanying an intramolecular Lewis acid-promoted spirocyclization of a propargylic silane
Spence, John D.,Lowrie, Lee E.,Nantz, Michael H.
, p. 5499 - 5502 (1995)
An intramolecular Lewis acid-promoted conjugate addition of a propargylic silane to a functionalized cyclohex-2-en-1-one resulted in part in the remarkable formation of a highly fused cyclobutene. The reaction was found to be dependent on the stoichiometr
INTRAMOLECULAR CYCLIZATIONS OF ALLYL- AND PROPARGYLSILANES
Schinzer, Dieter,Solyom, Sandor,Becker, Marion
, p. 1831 - 1834 (2007/10/02)
Allylsilanes of type 5 and propargylsilanes of type 13 undergo efficient cyclizations upon treatment with EtAlCl2 in toluene to afford stereoselectively functionalized hydrindanones of type 6 and spirodecanes of type 14.
