We have developed a fluorinated 2,6-xylenesulfonyl group (fluorinated xysyl, fXs) as a protective group for amines. The sulfonyl group could be attached to amines by reactions with the corresponding sulfonyl chloride, and survived various conditions, including acidic, basic, and even reductive conditions. The fXs group could be cleaved by treatment with a thiolate under mild conditions.
我们开发了氟化 2,6-二甲苯磺酰基(氟化 xysyl,f Xs)作为胺的保护基团。磺酰基可以通过与相应的磺酰氯反应连接到胺上,并在各种条件下存活,包括酸性、碱性甚至还原条件。f Xs基团可以通过在温和条件下用硫醇盐处理来裂解。
