Reverse regioselectivity: The first catalytic asymmetric C-1 functionalization of 1,3-dicarbonyl compounds by an aldol reaction is described, which regioselectively affords 6-hydroxyhexane-2,4-dione derivatives as the only product with high optical purity of up to 93 % ee. Furthermore, this ...
A simple, efficient procedure is proposed for Knoevenagel condensations of 1,3-dicarbonyl compounds with aldehydes catalyzed by heterogeneous polystyrene-supported aluminum chloride (Ps-AlCl3) under solvent-free conditions. The condensations are carried out smoothly with high yields (87–98%) at 60 °...
