2-iodo-glycals has been developed taking formic acid as a carbonyl source for the synthesis of 2-carboxylic acids of sugars by the hydroxycarbonylation strategy. The methodology was successfully extended to the synthesis of 2-formyl glycals by using a reductive carbonylation approach. Both ester and ether protected glycals undergo the reaction and furnished sugar acids in good yield which is otherwise
已经开发了以
甲酸为羰基来源的 Pd 催化的 2-
碘糖的羰基化反应,用于通过羟基羰基化策略合成糖的 2-
羧酸。通过使用还原羰基化方法,该方法成功地扩展到 2-甲酰基糖醛的合成。酯和醚保护的糖醛都进行反应并以良好的产率提供糖酸,这在文献方法中是不可能的。C-2 糖酸已成功用于通过 Ugi 反应构建 2-酰胺糖基、2-二肽-糖基和 C-1 和 C-2 支链糖基酯。
