thionylation – hetero-Diels–Alder domino reaction using α,β-unsaturated ketones with 1,2,3-triazole substituents, namely, 3-[2-(allyloxy)phenyl]-1-(1-aryl-5-methyl-1H-1,2,3-triazol-4-yl)-prop-2-en-1-ones, leading to 3,4-dihydro-2Н-thiopyranes and thiopyrano[3,4-с]chromenones. Variants of intra- and intermolecular cycloaddition were studied, as well the stereo- and regioselectivity of such reactions was assessed
我们已经开发出了硫酰化反应–杂Diels – Alder多米诺反应,使用具有1,2,3-三唑取代基的α,β-不饱和酮,即3- [2-(烯丙氧基)苯基] -1-(1-芳基- 5-甲基-1H-1,2,3-三唑-4-基)-丙-2-烯-1-酮,生成3,4-二氢-2Н-噻喃并噻吩并[3,4-с] chromenones 。研究了分子内和分子间环加成的变体,并评估了此类反应的立体和区域选择性。
