A New Class of Amino Protecting Group Removable by Reductive Acidolysis: the 4-Methylsulphinylbenzyloxycarbonyl (Msz) Group
A safety-catch type of amino protecting group, the 4-methylsulphinylbenzyloxycarbonyl (Msz) group is stable under both acidic and basic conditions, but can be smoothly removed by a one-pot reaction involving reductive acidolysis using tetrachlorosilane-tr
