Yang, Xu-Heng published the artcileCopper-catalyzed alkynylation/annulation cascades of N-allyl ynamides: regioselective access to medium-sized N-heterocycles, Recommanded Product: 7-Bromohept-1-yne, the publication is Organic Chemistry Frontiers (2021), 8(1), 18-24, database is CAplus.
A synthetic strategy based on sequential application of aza-Claisen rearrangement, C-H functionalization, C-N coupling and cyclization as key steps has been developed for the synthesis of various medium-sized N-heterocycles of pharmaceutical relevance. This efficient new method exhibits a broad scope and provides a highly efficient synthesis of N-heterocycles I [R1 = (4-methylbenzene)sulfonyl, naphthalene-2-sulfonyl, thiophene-2-sulfonyl, etc.; R2 = H, Me; R3 = C6H5, 4-ClC6H4, thien-2-yl, etc.; R4 = H, Me; X = (CH2)n; n = 0, 1, 2, 3] of different ring sizes (6-, 7-, and 8-membered rings) in moderate to good yields.
