An efficient synthetic method for the preparation of multisubstituted furans, thiophenes, and pyrroles using ynolates was developed. This novel formal [4 + 1] annulation by C2-C3 and C3-C4 bond formations includes cycloaddition, cyclization, decarboxylation, and dehydration as key steps.
开发了一种使用合成酸酯制备多取代呋喃,噻吩和吡咯的有效合成方法。通过C2-C3和C3-C4键形成的这种新颖的正式[4 +1]环化过程包括关键步骤:环加成,环化,脱羧和脱水。
