Reactions of thieno[2,3-с]pyrrolines with dehydrobenzene
Thieno[2,3-c]pyrrolines bearing a branched substituent at the nitrogen atom reacted with dehydrobenzene, furnishing thienylaziridines. N-Benzyl-substituted thienopyrroline under the reaction conditions gave a Stevens rearrangement product, 6-benzyl-5-phenylthieno[2,3-c]-pyrroline.
