to allylic trichloroacetimidates bearing a 2-allylaminoaryl group from readily available 2-iodoanilines combined with a one-pot multibond forming process has allowed the efficient synthesis of a series of 5-amino-2,5-dihydro-1H-benzo[b]azepines. The potential of these compounds as synthetic building blocks was demonstrated by the preparation of a late-stage intermediate of the hyponatremia agent, mozavaptan
从容易获得的2-碘苯胺与一锅多键形成工艺相结合,可快速获得带有2-烯丙基氨基芳基的烯丙基三氯乙酰亚氨酸酯,从而有效地合成了一系列5-氨基-2,5-二氢-1H-苯并[ b ] ze。制备低钠血症药物莫扎伐普坦的后期中间体证明了这些化合物作为合成构件的潜力。
