Catalytic intermolecular aldol reactions of transient amide enolates in domino Michael/aldol reactions of nitroalkanes, acrylamides, and aldehydes

Three-component reactions of nitroalkanes, acrylamides, and aldehydes by using a catalytic amount of KOH in DMSO gave β′-hydroxy-γ-nitro amides. Mechanistic studies suggested that the reactions proceeded by domino Michael/aldol reactions. The highly nucle

COMPOUND INHIBITING DIPEPTIDYL PEPTIDASE IV

The invention aims to provide a dipeptidyl peptidase IV inhibitor which is satisfactory in respect of activity, stability and safety and has an excellent action as a pharmaceutical agent. The invention is directed to a compound represented by the following general formula or a pharmaceutically acceptable salt thereof: wherein R1 and R2 each represents hydrogen, an optionally substituted C1-6 alkyl group, or -COOR5 whereupon R5 represents hydrogen or an optionally substituted C1-6 alkyl group, or R1 and R2, together with a carbon atom to which they are bound, represent a 3- to 6-membered cycloalkyl group, R3 represents hydrogen or an optionally substituted C6-10 aryl group, R4 represents a hydrogen or a cyano group, D represents -CONR6-, -CO- or -NR6CO-, R6 represents hydrogen or an optionally substituted C1-6 alkyl group, E represents -(CH2)m- whereupon m is an integer of 1 to 3, -CH2OCH2-, or -SCH2-, n is an integer of 0 to 3, and A represents an optionally substituted bicyclic heterocyclic group or bicyclic hydrocarbon group.
