Regio- and diastereoselective synthesis of diverse spirocyclic indenes by cyclization with indene-dienes as two carbon building blocks

Organic & Biomolecular Chemistry, Journal Year: 2023, Volume and Issue: 21(33), P. 6681 - 6686

Published: Jan. 1, 2023

We report a base-promoted cyclization with indene-dienes as two carbon building blocks toward diverse spirocyclic indene scaffolds including hexacyclic spiroindenes bearing benzo pyran motifs and pentacyclic containing oxindole units in high yields excellent diastereoselectivities.
