This paper describes two new access routes to 5,6,7,8-tetrahydro-4H-thieno[2,3-d]azepine from 2-(2-thienyl)ethylamine or its N-(2-chlorobenzyl) derivative. One of these two syntheses involves a new ring expansion from a 6,7-dihydro[3,2-c]pyridinium derivative, chloromethylated in position 4.
本文描述了从2-(2-噻吩基)乙胺或其N-(2-氯苄基)衍生物到5,6,7,8-四氢-4 H-噻吩并[2,3- d ]氮杂的两条新途径。这两个合成之一涉及从在位置4进行氯甲基化的6,7-二氢[3,2- c ]吡啶鎓衍生物进行的新环扩环。
