In situ formed acetals facilitated direct Michael addition of unactivated ketones

TfOH-promoted synthesis of 1,5-diketones by the Michael reaction of unactivated ketones with chalcones has been described. Acetals formed under HC(OMe)3/TfOH conditions generate the required enol-equivalents for a smooth Michael reaction. A wide array of symmetrical and unsymmetrical 1,5-diketones has been synthesised.

A new Br?nsted acid derived from squaric acid and its application to Mukaiyama aldol and Michael reactions

Bis-N-trifluoromethanesulfonyl squaramide was prepared as a new bench-stable strong Br?nsted acid and applied to the Br?nsted acid-catalyzed Mukaiyama aldol and Michael reactions with silyl enol ethers. The resulting Mukaiyama aldol products of aldehydes

The first michael addition of metal ketone enolates to α,β- unsaturated esters under catalytic conditions: Tin enolate with a catalytic amount of tetrabutylammonium bromide
