three-component coupling reaction of aldehydes, amides and dienophiles (AAD reaction) has been developed. Compared to known protocols for this type of reaction, the use of aromatic solvents in the presence of dehydrating reagents allows an efficient synthesis of previously not accessible products. Condensation of ubiquitous available aldehydes and amides and subsequent Diels–Alder reactions with dienophiles
The three component coupling reaction of aldehydes, phenylacetamide and dienophiles gave the corresponding N-phenylacetamidocyclohexene derivatives in good yields (55–70%) and high regioselectivity. For the first time, enzymatickineticresolution of this class of compounds has been achieved. The enantioselective hydrolysis of 4-N-phenylacetylamino-cis-3a,4,7,7a-hexahydroisoindole-1,3-dione derivatives

An improved procedure for the three-component coupling reaction of aldehydes, amides, and dienophiles (AAD-reaction) has been developed. The use of microwave technology enables the endo-selective synthesis of N-acyl cyclohexenylamines via condensation of readily available aldehydes and amides, and subsequent Diels–Alder reaction with electron-deficient dienophiles in significantly improved yields.
