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 syntheticbuildingblocks 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。

Hegedus aza-Wacker indole synthesis, we were intrigued with the fate of the aminopalladation intermediate if syn β-hydrogen is made inaccessible or unavailable. In contrast to our previously reported β-carbon elimination, cyclization of a variety of 2-alkenylaniline substrates under electrophilic palladium conditions unexpectedly afforded C3-substituted indoles. This unusual 1,2-migratory process was

Palladium-catalyzed cascades of arylation/cyclization/desulfonation of ortho-aminocinnamate esters by using diaryliodonium salts afforded a wide range of 4-aryl quinolin-2(1H)-ones. As such, the desired 4-aryl quinolin-2(1H)-ones with potential biological activity has been synthesized in the yields of 34–96%.
