General description

2-Chlorobenzaldehyde undergoes alkynylation with phenylacetylene in the presence of catalytic ligands and dimethylzinc at 0°C to form binaphthyl-derived amino alcohols.

Application

2-Chlorobenzaldehyde has been used in generation of small focused library of diversely functionalized dihydropyrimidine derivatives via one-pot three-component Biginelli cyclocondensation of β-ketoesters, aldehydes and thioureas.
