order to increase the applications of the water-soluble active ester method, water-soluble acylating reagents, [p-(benzyloxycarbonyloxy)phenyl]dimethylsulfonium methyl sulfate, [p-(t-butoxycarbonyloxy)phenyl]dimethylsulfonium methyl sulfate and [p-(9-fluorenylmethyloxycarbonyloxy)phenyl]dimethylsulfonium methyl sulfate, were synthesized from of p-hydroxyphenyldimethylsulfonium methyl sulfate. These
为了增加水溶性活性酯法的应用,水溶性酰化试剂[对(苄氧基羰基氧基)苯基]二甲基硫酸锍、[对(叔丁氧基羰氧基)苯基]二甲基硫酸锍和[对- (9-芴基甲氧基羰基氧基)苯基]二甲基锍甲基硫酸盐由对羟基苯基二甲基锍甲基硫酸盐合成。这些化合物在水中具有高溶解度(超过 30%),并且被发现可作为优异的水溶性酰化试剂,用于在水溶液中合成 N-苄氧羰基、N-叔丁氧羰基、N-9-芴基甲氧羰基氨基酸衍生物。他们在水性介质和氨基酸中将二肽转化为 N-酰基二肽。此外,还发现它们是保护赖氨酸、鸟氨酸、
