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.

interdependencies of the most important reactor and reaction parameters. Unlike many commercial thin-film and microchannel reactors, the described set-up operates residence times of up to 30 min which cover the typical rates of many organic reactions. The tubular microreactor was successfully applied to the photooxygenation of hydrocarbons (Schenck ene reaction). Major emphasis was laid on the realization
