Cyclodimerization of α,β-unsaturated ketones catalyzed by lanthanoid tri-2-propoxides
Okano, Tamon,Ohno, Katsutoshi,Kiji, Jitsuo
, p. 1041 - 1042 (1996)
α,β-unsaturated ketones are cyclodimerized by the catalysis of lanthanoid tri-2-propoxides into substituted cycohexanones in good yields. The catalytic activity of the lanthanoids is fairly superior to those of the sodium or aluminum propoxides.
Michael Addition of Acyclic Lithium 1,3-Dien-2-olates with α,β-Unsaturated Esters, Ketones, and Diesters
Kanemasa, Shuji,Kumegawa, Masahiro,Wada, Eiji,Nomura, Masafumi
, p. 2990 - 3004 (2007/10/02)
The Michael addition of lithium 1,3-dien-2-olates with α,β-unsaturated carbonyl compounds is described.With α,β-unsaturated esters the reaction was reversible even at -78 deg C, while kinetically controlled with α,β-unsaturated ketones or alkylidenemalona
The Double Michael Reaction of α,β-Unsaturated Ketones with Siloxydienes Catalyzed by Trityl Perchlorate Forming Six-Membered Ring Systems
Mukaiyama, Teruaki,Sagawa, Yukihiro,Kobayashi, Shu
, p. 1821 - 1824 (2007/10/02)
In the presence of a catalytic amount of trityl perchlorate, the double Michael reaction of α,β-unsaturated ketones with siloxydienes smoothly proceeds to afford six-membered ring systems stereoselectively in good yields.Decalin derivatives are also obtai
