The present study describes the synthesis of phenanthro [3,4-b] thiophene (3), phenanthro[4,3-b]thiophene (4) andits potential dihydrodiol metabolites, trans-6,7-dihydroxy-6,7-dihydrophenanthro[3,4-b]thiophene (5) andtrans -8,9-dihydroxy-8,9-dihydrophenanthro[3,4-b]thiophene (6), trans-6,7-dihydroxy
## Abstract A new series of substituted 1,2,4βtriazoles bearing thiophene molecules **8** and **10** has been synthesized from cycloaddition of thiophene 3βand 2βcarbonitriles **5** and **9**, respectively, with the reactive cumulene intermediates **4**. The newly synthesized products have been eva
