Spirodiepoxide-Based Cascades: Direct Access to Diverse Motifs
摘要:
Allene epoxide formation/opening reaction sequences enabled direct access to diverse products. Described here are a single flask procedure for allene preparation and allene oxidation/derivatization reactions that give, among others, diendiol, diyndiol, alpha'-hydroxy-gamma-enone, dihydrofuranone, butenolide, and delta-lactone products.
