We have developed a straightforward FeCl3 promoted synthesis of dihydropyrrolo[2,1‐a]isoquinolinesthrough formal (3+2) cycloaddition/oxidative aromatization cascade of dihydroisoquinoline with Morita‐Baylis‐Hillman carbonates (up to 96% yield). Further modifications of the obtained products were successful through simple chemical transformations providing a diverse range of natural product‐like molecules
我们已经开发出一种简单的FeCl 3促进的二氢吡咯并[2,1- a ]异喹啉的合成,方法是通过二氢异喹啉与Morita-Baylis-Hillman碳酸盐的正式(3 + 2)环加成/氧化芳构化级联(产率高达96%)。通过简单的化学转化成功获得了进一步的修饰产物,提供了多种天然产物样分子(12个例子)。
Organocatalytic One-Pot Synthesis of Highly Substituted Pyridazines from Morita-Baylis-Hillman Carbonates and Diazo Compounds
A biologically inspired organocatalytic one‐pot synthesis of highly functionalized pyridazines, which are ubiquitous structural units in a number of biologically active compounds, has been developed by starting from readily available diazo compounds and Morita–Baylis–Hillman (MBH) carbonates. Under mild reaction conditions, this synthetic route tolerated significant substrate variation to deliver a
