“…Meanwhile, the yields of the products decreased in the order of para -substituent, meta -substituent, and ortho -substituent, probably due to the steric hindrance ( 7ba , 7la , and 7ia ). Considering the importance of heterocyclic compounds in medicinal chemistry, the furan [ 38 , 39 ], thiophene [ 40 , 41 , 42 , 43 ], and indole [ 44 , 45 , 46 , 47 ] moieties were all installed to the arenes, and the desired products 7na-7qa were furnished in 36–93% yields. On the other hand, the tolerance of vinylogous malononitrile derivative 3 were also investigated.…”
