In this study, the preparation of 4-imidoyl-, 4-oxiranyl-, and 4-propargyloxyphenyl-substituted β-lactams as versatile building blocks in heterocyclic chemistry was realized. Efforts were made to deploy these polyvalent compounds for ensuing cyclization reactions en route to new bi- or polycyclic frameworks, which, in the case of a 3-chloro-4-propargyloxyphenyl-β-lactam substrate, enabled the preparation
在这项研究中,实现了 4-亚胺酰基-、4-环氧乙烷基-和 4-炔丙基氧基苯基取代的 β-内酰胺作为杂环化学中多功能构建单元的制备。人们努力部署这些多价化合物,以确保在形成新的双环或多环框架的过程中发生环化反应,在 3-chloro-4-propargyloxyphenyl-β-lactam 底物的情况下,能够制备出前所未有的 β-内酰胺融合的苯并三唑并恶唑烷支架。后一种多杂环的化学结构通过 X 射线分析明确确定。
