A one-pot multibond-forming process involving a thermally mediated Overman rearrangement and a ring closing metathesis reaction of allylic trichloroacetimidates bearing a 2-allyloxyaryl group has been developed for the synthesis of 5-amino-substituted 2,5-dihydro-1-benzoxepines. Chemoselective reduction and functionalization of these compounds allowed access to a range of pharmacologically active 5-amino-2
已开发出一种涉及热介导的超人重排和带有2-烯丙氧基芳基的烯丙基三氯乙亚氨酸酯的闭环易位反应的一锅多键形成工艺,用于合成5-氨基取代的2,5-二氢-1-苯并x庚因。这些化合物的化学选择性还原和功能化使得可以使用一系列具有药理活性的5-氨基-2,3,4,5-四氢-1-苯并x庚因支架。
