DBU-promoted [3+2] cycloaddition for the synthesis of trispiro heterocycles from acetylpyrazolyl-substituted oxindoles and substituted isatins

Year: 2026

Type: article

Abstract: DBU-promoted [3+2] annulation of 3-pyrazolyl oxindoles with isatins constructs privileged 3,3′-polyspiro oxindole-γ-butyrolactones, featuring mild conditions, broad scope, and scalability.
