Regioselective synthesis of 1,7-diprotected 1,4,7,10-tetraazacyclododecane and preparation of a dialcohol dicarboxylic macrocyclic ligand

The reaction of 1,4,7,10-tetraazacyclododecane with p-toluenesulfonyl chloride in pyridine or with diethyl phosphite and CCl4 in a water/CH2Cl2 mixture yields selectively the 1,7-diprotected regioisomer.The 1,7-diprotected tetraaza cycles are interesting
