已经发现,与标准的热传导相比,微波辅助合成通过更有效的加热可以提高反应速率和产率。Isatin与thiosemicarbazide以及它们的thiosemicarbazone与仲胺在酸上的干反应-在微波炉中洗涤K10,可以得到相当好的产率的isatin-3-thiosemicarbazones和N-Mannich碱。化学结构通过1 H NMR,IR光谱数据和元素分析得到确认。J.杂环化学。,46,571(2009)。

A simple, rapid, and efficient method for the synthesis of some new thiazolidinone and thiohydantoin derivatives of isatins along with some Mannich bases has been achieved in excellent yield from indole-2,3-dione-3-thiosemicarbazone employing microwave irradiation.
