摘要：

''Tailor-made'' carbonyl ylides bearing only alkyl snbstituents or no substituents were efficiently generated from alpha-chloroalkyl alpha'-chloroalkyl ethers in the presence of samarium reagents. Using these novel and synthetically practical carbonyl ylides, optionally substituted and stereochemically defined tetrahydrofurans, dihydrofurans and dioxolane were synthesized in a single Step.
