In one-pot cascade reaction, a series of functionalized 3-aroyl-4-hydroxy-4-arylpiperidine derivatives were prepared from sulfonamides and vinyl ketones with good to excellent yields and diastereoselectivities. The reaction was catalyzed by the commercially available Lewis base 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) and could be easily manipulated under mild condition.

An iodine-catalyzed coupling of β-hydroxyketones with aromatic amines to yield β-aminoketones and benzo[h]quinolones had been developed. Noble metallic catalysts, oxidants, α β-unsaturated ketone intermediates and aza-Michael addition were not involved in this coupling reaction which made it unique when compared to other reactions reported in literature. Inexpensive iodine catalyst, easy accessible raw materials, mild reaction conditions, good functional group tolerance and excellent selectivity made this coupling reaction be a practical method. This reaction can also be scaled up.

supporting information, p. 2669 - 2673 (2013/06/05)
A general and efficient aza-Michael reaction promoted by aqueous sodium carbonate solution has been developed. The reaction has complete mono-alkylation selectivity and proceeds with complete chirality retention for chiral amino esters. With a broad substrate scope, a well-common catalyst and simple operation, the catalytic approach provides a facile, practicable, economical, and environmentally benign method for the synthesis of β-amino carbonyl compounds.
