  Glycosylations of Cyclopropyl-Modified Carbohydrates: Remarkable β-Selectivity Using a Mannose Building Block

  摘要：

  A mannosyl donor bearing a spiroannulated cyclopropane unit at C-5 has been prepared, and its behavior in glycosylation reactions investigated. Selectivities in favor of the beta-anomer were observed. Corresponding di- and trisaccharides incorporating the rigid cyclopropane motif were assembled.
