  Microwave-Assisted Synthesis and Crystal Structure of Novel 2-Dichloromethyl-1,3-dioxolanes

  摘要：

  An efficient synthesis of 2-dichloromethyl-1,3-dioxolane derivatives with microwave-assisted addition reaction was developed. The intermediate 1,3-dioxolanes 2 were obtained by exposing to microwave radiation with glycol at the present of anhydrous CuSO4. A series of novel 2-dichloromethyl-1,3-dioxolane derivatives 3 were synthesized by carbenes insertion of dioxolanes 2 and chloroform with TEBA used as phase transfer catalyst. The structures of the compounds were characterized by IR, H-1-NMR, C-13-NMR spectroscopy, and elemental analysis. The configuration of 3f was determined by X-ray crystallography.
