Synthesis of α-d-C-glucoside employing dichloroketene cycloaddition and Baeyer-Villiger oxidation

Abstract The cycloaddition of dichloroketene to glucal followed by Baeyer-Villiger oxidation gave a bicyclic γ-lactone, an α- d -C- glucoside , which was further transformed to glucitol under the Suarez protocol.

Synthesis of α--C-glucoside employing dichloroketene cycloaddition and Baeyer-Villiger oxidation

A short synthesis of bicyclic sugar pyrimidine nucleosides from C-glycosides

Abstract The C -glycosides were prepared from dichloroketene cycloaddition reaction to glycals and converted to bicyclic sugar nucleosides in good yields.

A ONE-POT CONVENIENT PROCEDURE FOR THE SYNTHESIS OF C-GLYCOSIDE VIA CYCLOADDITION OF DICHLOROKETENE TO GLYCAL AND DECHLORINATION OF THE CYCLOADDUCT

ABSTRACT A convenient procedure for the synthesis of C-glycoside was developed via cycloaddition of dichloroketene, generated in situ, to glycal and dechlorination of the cycloadduct using zinc and acetic acid.

One-pot synthesis of cinnamic anhydrides from cinnamic acids and 6-chloro-2,4-dimethoxy-sec-triazine (CDMT) at room temperature

ABSTRACT Symmetric cinnamic anhydrides were prepared by the reactions of cinnamic acid substrates with 6-chloro-2,4-dimethoxy-sec-triazine. The reactions were performed at room temperature for 15 h. Diverse cinnamic acid substrates bearing electron-withdrawing or -donating groups worked well, providing the corresponding cinnamic anhydrides in moderate-to-good yields GRAPHICAL ABSTRACT
