摘要

A novel rearrangement was discovered by reacting 1,4-diazaspiro-[4,5]-decan-2-ones with a Vilsmeier-Haack reagent to give previously unknown aminoquinoline derivatives. The reaction proceeds as an electrophilic rearrangement under mild conditions with a satisfactory yield of reaction products. (c) 2021 Elsevier Ltd. All rights reserved.
