Microwave irradiation applied with success to cycloaddition reaction of N-Propargyl-N-p-tolyl-N-2-furfurylamines
The new N-(5-substituted.2-furfuryl)-N-prop-2-ynyl-p-toluidines were prepared according to the reported procedure and intramolecular Diels-Alder reaction was performed by heating a benzene solution of the amines under nitrogen for three days.The intramolecular Diels-Alder reaction of the 5-H and 5-CH3 substituted amines was also performed under microwave irradiation conditions giving the cycloaddition products 5-H and 5-CH3 substituted N-p-tolyl-5-methyl-5, 7a-dihydro-5, 7a-epoxyisoindolines. Comparing the results of the usual thermal and the MAOS reaction, we confirmed our expectations that MAOS could promote the outcome of IMDA reaction of the suitably N-substituted tertiary 2-furfuryl-amines.
