Abstract
The syntheses of novel spiro-linked quinolinone-pyrrolidine/pyrrolo[1,2-c]thiazole-oxindole/acenaphthalene hybrid heterocycles have been achieved through a one-pot three-component [3 + 2] cycloaddition strategy. The reaction proceeded stereoselectively affording these structurally intriguing multi-spiro compounds in excellent yields. (C) 2018 Elsevier Ltd. All rights reserved.
