Organic Reactions at High Pressure. Dipolar Cycloaddition-Ring Contraction Reactions of Hindered Silyl Enol Ethers and Arylsulfonyl Azides

Article abstract of DOI:10.1021/jo00146a051

Dipolar cycloaddition of arylsulfonyl azides with sterically congested silyl enol ethers at 15 kbar (1.5 GPa) in acetonitrile/methylene chloride cleanly affords good yields of one-carbon ring-contracted products.
