diastereoselectivity and high regioselectivity for coupling at the more substituted allyl terminus. It is proposed that this unusual combination of selectivities results from a tandem allylation/aza-Cope rearrangement sequence. After allylation, decarboxylative dearomatization produces an intermediate for the aza-Cope rearrangement. The subsequent aza-Cope rearrangement occurs under mild conditions
杂芳族烷烃的烯丙酯进行容易的钯催化脱羧偶联。形成的 C-C 键具有高非对映选择性和高区域选择性,用于在更多取代的烯丙基末端偶联。提出这种不寻常的选择性组合是由串联烯丙基化/氮杂-Cope 重排序列引起的。烯丙基化后,脱羧脱芳构化产生氮杂-科普重排的中间体。随后的 aza-Cope 重排发生在温和的条件下,因为它是由重构化驱动的。
