The discovery, syntheses, and structure–activity relationships (SAR) of a new family of heterocyclic antibacterial compounds based on N-alkyl-N-(pyridin-2-yl)hydroxylamine scaffolds are described. A structurally diverse library of ∼100 heterocyclic molecules generated from Lewis acid-mediated nucleophilic ring-opening reactions with nitroso Diels–Alder cycloadducts and nitroso ene reactions with substituted

Conjugatedtrienes are fascinating building blocks for the rapid construction of complex polycyclic compounds. However, limited success has been achieved due to the challenging regioselectivity control. Herein, we report an enantio- and diastereoselective process allowing to regioselectively control the functionalization of NH-triene-carbamates. Synthesis of chiral cis-3,6-dihydro-2H-1,2-oxazines is
共轭三烯是快速构建复杂多环化合物的令人着迷的构建模块。然而,由于具有挑战性的区域选择性控制,取得的成功有限。在此,我们报告了一种对映选择性和非对映选择性过程,可以区域选择性地控制N H-三烯-氨基甲酸酯的官能化。手性顺式-3,6-二氢-2H -1,2-恶嗪的合成是通过手性磷酸催化的亚硝基-Diels-Alder环加成反应实现的,涉及[(1 E ,3 E ,5 E )-hexa-1, 3,5-三烯-1-基]氨基甲酸酯。此外,通过仔细选择反应条件,可以模块化获得具有优异非对映选择性和高至优异对映选择性的三种不同区域异构体。计算研究表明,区域选择性受到三烯 6 位取代基的空间需求以及两个环加成伙伴之间的非共价相互作用的影响。各种合成转化突出了每种区域异构环加合物的实用性。
