Facile synthesis of 3,4-dihydro-α-pyrones via Michael reaction-O-acylation sequences
Kobayashi, Shu,Moriwaki, Mitsuhiro
, p. 551 - 552 (2007/10/03)
3,4-Dihydro-α-pyrones were prepared in excellent yields with high stereoselectivities by the trityl salt-catalyzed Michael reaction and sequential intramolecular O-acylation of the intermediary silyl enol ethers using a mercury (II) salt (one-pot reaction
The Highly Stereoselective Michael Reaction of α,β-Unsaturated Ketones with Silyl Enol Ethers of Thioesters Catalyzed by Trityl Salts. A Facile Stereoselective Synthesis of 5-Oxocarboxylic Acid Ester Derivatives
Mukaiyama, Teruaki,Tamura, Masanori,Kobayashi, Shu
, p. 1817 - 1820 (2007/10/02)
In the presence of a catalytic amount of trityl salts, silyl enol ethers of thioesters stereoselectively react with α,β-unsaturated ketones to afford the Michael adducts in high yields. 5-Oxocarboxyclic acid ester derivatives, useful synthetic precursors
