extend the available orthogonalities within the class of protecting groups removed by assisted cleavage. The mild, complementary (oxidative vs reductive) reaction conditions for the removal, together with their pivaloate-like character, were exploited, in combination with a levulinoyl-ester functioning as a third orthogonal protecting group, in the assembly of a Streptococcus mutans hexasaccharide
开发了标题化合物以在通过辅助裂解除去的保护基类别内扩展可用的正交性。在组装变形链球菌六糖的过程中,开发了温和的,互补的(氧化与还原)反应条件及其类似新戊酸酯的特征,并结合了用作第三个正交保护基的乙酰丙酸酯。从具有β-葡萄糖基附肢的寡头羊骨干骨架中提取出来。
