Abstract :A series of pyrazolidinium ylides was reacted with benzothiophene 1,1-dioxide to afford insert ignore into journalissuearticles values(3R,5S,5aS,10bS);-3-methyl-5-substitutedphenyl-2,3,5,5a-tetrahydrobenzo[4,5]thieno[3,2-c]pyrazolo[1,2-a]pyrazol-1insert ignore into journalissuearticles values(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.
