Reported herein is a novel 4-OTBS benzyl-based protective group for carboxylic acids. This protective group can be removed in the presence of TBAF or TFA with high efficiency, which makes it compatible with base-sensitive or acid-sensitive substrates. With this protective group, a near-infrared fluorogenic probe for the detection of γ-glutamyltranspeptidase activities was readily prepared.
本文报道了一种新颖的基于4-OTBS苄基的羧酸保护基。可以在TBAF或TFA存在下高效去除该保护基,这使其与碱敏或酸敏底物兼容。利用该保护基,可以容易地制备用于检测γ-谷氨酰转肽酶活性的近红外荧光探针。
