Microwave-assisted regioselective [1,3]-dipolar cycloaddition of 3-methyl-2-(substitutedbenzylidene)-5-oxopyrazolidin-2-ium-1-ides to benzothiophene 1,1-dioxide
A series of pyrazolidinium ylides was reacted with benzothiophene 1,1-dioxide to afford (3R,5S,5aS,10bS)-3-methyl-5-substitutedphenyl-2,3,5,5a-tetrahydrobenzo[4,5]thieno[3,2-c]pyrazolo[1,2-a]pyrazol-1(10bH)-one 6,6-dioxides under microwave irradiation and their structures were identified by means of spectral/physical characteristics including X-ray diffraction data and HRMS measurements.
