acids can catalyze numerous reactions including the aldol reaction, the Mannich reaction, an α-amination, an α-aminoxylation, the Diels Alder reaction, and an asymmetric conjugate addition. Besides, the salts of proline or modified amino acids exhibit catalytic activities towards Michael addition of nitroalkanes to enones or enals. The products of Michael addition of nitroalkanes provide a variety of key

A multifunctionalization of unactivated cyclicketonesvia synergistic catalysis of copper and diarylamine for the direct synthesis of cyclic α-enaminone is reported for the first time. This reaction goes through oxidative α-amination, followed by a desaturation, and features mild reaction conditions, a broad substrate scope, and great functional group tolerance.
The Michael addition of nitroalkanes to alpha,beta-unsaturated enones catalyzed by a novel chiral imidazolidine-2-yltetrazole organocatalyst has been investigated. The new more soluble organocatalyst decreases reaction times and improves enantioselectivities compared to other catalysts. The Michael addition adducts were obtained with up to 92% ee.
