Hydrogenation of a series of cyclic β-(acylamino)acrylates with tetrasubstituted olefins has been accomplished successfully with the use of Ru catalysts with chiral biaryl ligands such as C3-TunaPhos, and up to over 99% ee's have been achieved. This methodology provides an efficient catalytic method for the synthesis of both cis and trans chiral cyclic β-amino acid derivatives. Copyright
Efficient synthesis of β-amino-α,β-unsaturated carbonyl compounds

, p. 769 - 772 (2007/10/03)
A versatile and high-yielding procedure for the synthesis of β-enamino esters and β-enaminones is presented: in the presence of tetraethyl orthosilicate, a number of highly functional β-enamino esters were obtained; this method provided an alternative for the formation of β-amino-α,β-unsaturated carbonyl compounds with mild and functional group compatible reaction conditions.
