Diguanidinocalix[4]arenes as effective and selective catalysts of the cleavage of diribonucleoside monophosphates†
Abstract
Calix[4]arenes derivatives 1 and 2, featuring two guanidine units at the upper rim, catalyze the transesterification of diribonucleoside monophosphates much more effectively than that of HPNP. Rate accelerations relative to the background range from 103 to 104-fold, and approach 105-fold with the most favorable substrate-catalyst combinations.
