Heterocyclic compounds can be divided into two categories: alicyclic heterocycles and aromatic heterocycles. Compounds whose heterocycles in the molecular skeleton cannot reflect aromaticity are called alicyclic heterocyclic compounds. Compound: 132098-59-0, is researched, Molecular C19H18N2O2, about Chiral Calcium Complexes as Bronsted Base Catalysts for Asymmetric Addition of α-Amino Acid Derivatives to α,β-Unsaturated Carbonyl Compounds, the main research direction is Michael addition product enantioselective preparation; pyrrolidine enantioselective preparation; asym addition reaction cycloaddition amino acid unsaturated carbonyl compound; chiral calcium complex asym addition reaction cycloaddition.Computed Properties of C19H18N2O2.
A novel catalyst system based on complexes of calcium which promote the catalytic asym. 1,4-addition reactions and [3+2] cycloaddition reactions of α-amino acid derivatives with α,β-unsaturated carbonyl compounds have been developed. The reactions proceeded smoothly in the presence of 5-10 mol % of the chiral calcium catalyst to afford the desired adducts in high yields with high diastereo- and enantioselectivities. A wide range of α,β-unsaturated esters and amides were applicable, and other glycine and even dl-alanine derivatives reacted with several α,β-unsaturated carbonyl compounds to afford the corresponding substituted pyrrolidine derivatives in high yields with excellent diastereo- and enantioselectivities. In the reactions with dl-alanine derivatives, quaternary asym. carbons were constructed efficiently.
