Novel 7- and 8-alkyl and aryl substituted 5-phenylmorphans were synthesized from substituted allyl halides and N-benzyl-4-aryl-1,2,3,6-tetrahydropyridine by a highly efficient and diastereoselective reaction series, “one-pot” alkylation and ene-imine cyclization followed by sodium borohydride reduction. Mild cyclization conditions gave the desired substituted 5-phenylmorphans in good yield as a single
由取代的烯丙基卤化物和N-苄基-4-芳基-1,2,3,6-四氢吡啶通过高效的非对映选择性反应系列“一锅”烷基化和烯-亚胺环化,然后硼氢化钠还原。温和的环化条件以良好的收率得到所需的取代 5-苯基吗喃,为单一非对映异构体。
