Synthesis and conformation of dithia[3]metacyclo[3]thiophenophanes and [2]metacyclo[2]thiophenophanes
摘要:
Dithia[3]metacyclo[3]- -(2,3)-, -(2,4)-, -(2,5)-, and -(3,4)thiophenophanes were prepared by dithiol bis-alkylations and were oxidized with m-chloroperbenzoic acid to the corresponding tetraoxides. Pyrolysis of the tetraoxides under a reduced pressure gave the corresponding [2]metacyclo[2]thiophenophanes together with many unexpected compounds. The conformations of the obtained products are also discussed.

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.
在氮原子上带有支链取代基的噻吩并[2,3- c ]吡咯啉与脱氢苯反应,得到噻吩并氮丙啶。在反应条件下,N-苄基取代的噻吩并吡咯啉得到史蒂文斯重排产物6-苄基-5-苯基噻吩并[2,3- c ]-吡咯啉。
