An organocatalytic Michael/aza-Michael cascade reaction was developed to build the functionalized quinolizine scaffolds in 60–82% yields, excellent diastereoselectivities, and E/Z selectivities. This protocol involves the [3 + 3] annulations of 2-pyridylacetates with nitroenynes through the dearomative strategy in the presence of an organic base under mild conditions. The versatile late-stage derivatizations
Base-Promoted Decarboxylative Annulation of Methyl 2-(2-Bromophenyl)acetates and Ynones to Access Benzoxepines

日期:2023.3.3
decarboxylative annulation of ynones with methyl 2-(2-bromophenyl)acetates has been developed. A broad range of benzoxepines were prepared with a broad substrate scope and high regioselectivity in moderate to excellent yields under transition-metal-free conditions. This method proceeds through a tandem [2 + 4] annulation, ring-opening decarboxylative reaction, and the intramolecular nucleophilic aromatic substitution
已开发出一种简单有效的碱基介导的炔酮与 2-(2-溴苯基) 乙酸甲酯的脱羧环化反应。在无过渡金属的条件下,以中等至优异的收率制备了多种具有广泛底物范围和高区域选择性的苯并氧杂环庚烷。该方法通过串联[2+4]环化、开环脱羧反应和分子内亲核芳香取代反应进行。此外,关键中间体已成功获得并通过单晶 X 射线晶体学明确表征,这有利于支持脱羧环化机制。此外,还研究了进一步功能化的克级反应和合成应用。
