Spirooxindoles as Potential Pharmacophores

Mini-Reviews in Medicinal Chemistry, 2017
The spiroindole heterocyclic scaffold is found in many natural products and has been identified as an important bioactive agent. Over the past few decades, various spiroindole-containing compounds have been reported to possess biological properties and hence found in the structure of many synthetic pharmaceuticals.

Therapeutic Potential of Spirooxindoles as Antiviral Agents [PDF]

open access: yesACS Infectious Diseases, 2016
Antiviral therapeutics with profiles of high potency, low resistance, panserotype, and low toxicity remain challenging, and obtaining such agents continues to be an active area of therapeutic development. Due to their unique three-dimensional structural features, spirooxindoles have been identified as privileged chemotypes for antiviral drug ...

Enantioselective Construction of Spirooxindole-Fused Cyclopentanes

The Journal of Organic Chemistry, 2021
The present study reports an asymmetric organocatalytic cascade reaction of oxindole derivates with α,β-unsaturated aldehydes efficiently catalyzed by simple chiral secondary amine. Spirooxindole-fused cyclopentanes were produced in excellent isolated yields (up to 98%) with excellent enantiopurities (up to 99% ee) and moderate to high ...

A New Route to Spirooxindoles

Organic Letters, 2000
[reaction: see text]Reaction of indole amides 5 with tributylstannane gave spiroindolenines 9 which are readily converted into spiropyrrolidinyloxindoles. This tricyclic system is found in a number of interesting natural products.

Strategies for the enantioselective synthesis of spirooxindoles

Organic & Biomolecular Chemistry, 2012
Oxindoles and spirooxindoles are important synthetic targets that are often considered to be prevalidated with respect to their biological activity and applications for pharmaceutical lead discovery. This review features efficient strategies for the enantioselective synthesis of spirocyclic oxindoles, focusing on reports in 2010 and 2011.

Diastereoselective Synthesis and Structure of Spirooxindole Derivatives

HETEROCYCLES, 2003
Spiroindolinonisoxazolines (4 and 5h) are prepared from (E)- 1 or (Z)-3-arylidene-2-oxindoles (2) by nitrile oxide cycloaddition reactions. Only one regioisomer is detected in all cases, and the observed complete diastereoselection is established by unambigous structural assignments.

An Access to Highly Functionalized Dihydrobenzofuran Spirooxindole Scaffolds

Organic Letters, 2022
We have developed an efficient protocol for the construction of polycyclic dihydrobenzofuran spirooxindole scaffolds via base promoted cascade annulation of Morita-Baylis-Hillman (MBH) carbonates of isatins with ortho-hydroxychalcones or ortho-hydroxy-β-nitrostyrenes. The complex polycyclic compounds were conveniently synthesized in satisfactory yields
