A Pd-catalyzed asym. aromative [4+3]-cyclization reaction of amino-trimethylenemethanes (CH3)3COC(O)OCH2C(=CH2)CH2N=C(C6H5)2 (TMM, 1,3-dipoles) with fused 1-azadienes I (X = O, CH2; R = Ph, thiophen-2-yl, naphthalen-1-yl, etc.) has been developed. This method enables access to the synthetically importance and biol. active benzofuran fused azepines II (X = O) and indeno-azepines II (X = CH2) in excellent efficiency and stereoselectivity (up to 95% yield, 99% ee, >19 : 1 dr). After reading the article, we found that the author used Tris(dibenzylideneacetone)dipalladium(0)(cas: 51364-51-3Application In Synthesis of Tris(dibenzylideneacetone)dipalladium(0))
Tris(dibenzylideneacetone)dipalladium(0)(cas: 51364-51-3) is the most widely used PdO precursor complex in synthesis and catalysis, in particular as a catalyst for various coupling reactions. Application In Synthesis of Tris(dibenzylideneacetone)dipalladium(0) It also used for palladium-catalyzed one-pot synthesis of tricyclic indolines, in the Suzuki-Miyaura coupling of 2-pyridyl nucleophiles and cross-coupling of aryl halides with aryl boronic acids.
