  Total synthesis of the 2-arylbenzo[b]furan-containing natural products from Artocarpus

  摘要：

  In this study, 2-arylbenzo[b]furan-containing derivatives moracin C (1) and moracin M (4), the natural products from Artocarpus, have been synthesized in highest overall yield to date (1, 7 steps with an overall yield of 41.9%; 4, 6 steps with an overall yield of 56.3%), and we also report the first total synthesis of artoindonesianin B-1 (2), another member of this family, in the same route (8 steps with an overall yield of 11.3%). This discovery provides a concise route for preparing enough amounts of 1, 2, and 4 as well as 2-arylbenzo[b]furan-containing natural product-like analogs (71-74) to explore the biological potential.

  Pd‐catalyzed Hiyama vinylation reaction of non‐activated aryl chlorides and bromides under mild conditions was developed. The use of efficient vinyl donors and electron‐rich sterically hindered phosphine ligands was critical for the success of the reaction.

  simple and effective Pd(II)-catalyzed regioselective C(2)–H arylation of 6,5-fused heterocycles with dioxazolones as a masked ester surrogate under mild conditions is reported. The significance of the arylation is highlighted by the new reactivity demonstrated in dioxazolones via proximal C–H activation of the cyclic carbonate of the hydroxamic acid functionality under protic conditions.

  日期：2021.11

  We developed a protocol for the palladium-catalyzed aminocarbonylation of aryl halides using less-toxic formamide acetals as bench-stable aminocarbonyl sources under neutral conditions. Various aryl (including heteroaryl) halides reacted with N,N-dialkylformamide acetals in the presence of a catalytic amount of tris(dibenzylideneacetone)dipalladium(0)-chloroform adduct and xantphos to give the corresponding
