Chiral Allyl Cations Are Capture by Furan with 100% Stereoselectivity: Synthesis of Enantiopure 2-Alkoxy-8-oxabicyclo[3.2.1]oct-6-en-3-ones by Low-Temperature [4+3] Cycloaddition

A low-temperature (-95°C) protocol for intermolecular cycloadditions of furan to chiral silyloxyallyl cations in dichloromethane is described. Key precursors are open-chain, mixed α-ketoacetals, which are chiral. The resulting [4+3] cycloadducts are dense
