Abstract
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.
