Axelsson, Anton,Hammarvid, Emmelie,Rahm, Martin,Sundén, Henrik
, p. 5436 - 5444 (2020)
We present a general protocol for the formal Michael addition of acetone to α,β-unsaturated esters and amides, a transformation difficult to perform using current methods. The protocol comprises of an amidine catalyzed relay ring-opening and fragmentation

Wascholowski, Veit,Knudsen, Kristian Rahbek,Mitchell, Claire E. T.,Ley, Steven V.
experimental part, p. 6155 - 6165 (2009/05/27)
A general enantioselective organocatalytic conjugate addition procedure of a variety of malonates to α,β-unsaturated enone systems is presented. The reaction is efficiently catalysed by the pyrrolidinyl tetrazole catalyst 1. Cyclic, acyclic and aromatic e
