Protective groups are provided which are suitable for masking phosphates and phosphonates. The protected compositions can be introduced in a biological system and then demasked under certain biological conditions. This method permits phosphates and phosphonates which would themselves degrade in the biological system and therefore be ineffective to be introduced in a protected form and late released under the proper conditions.
提供适用于掩蔽磷酸盐和膦酸盐的保护基团。所保护的组合物可以被引入生物系统,然后在特定的生物条件下去除掩蔽基团。该方法允许磷酸盐和膦酸盐以保护形式引入,然后在适当条件下晚些时候释放,这些磷酸盐和膦酸盐本身在生物系统中会分解,因此无效。
