The invention relates to ÿ-substituted porphyrins, methods for their synthesis, and their use in the preparation of photoelectric materials. In particular, the invention relates to solid state photoelectric devices, including solar cells and photodetectors, incorporating these photoelectric materials, with improved photon-to-current conversion efficiencies.
malonates to in situ generated N-formylimines of aromatic aldehydes was achieved underphase-transfercatalysis using Cinchona alkaloids-derived quaternaryammoniumsalts. The resulting β-formamidomalonates have been efficiently converted into β-aryl-β-isocyano esters. Their utility in the multicomponent Ugi reaction with chiral cyclic imines has been demonstrated.

The highly enantioselectivereaction between in situ generated, Cbz-protected azomethines and malonates in the presence of 150 mol % of potassium carbonate (50 % w/w) and 1 mol % of quinine-derived quaternary ammonium bromides as phase-transfer organocatalysts has been developed. This study reports a novel approach for the asymmetric Mannich-type reaction and a wide range of azomethines, including
