Abstract:

Two new chiral macrocyclic ligands containing the pyrimidine subcyclic unit Figure 1 have been prepared. Chiral dimethyl-substituted pyrimidino-crown 1 was prepared from 4-methoxy-5-methyl-2,6-pyrimidinedimethyl ditosylate 3 and chiral dimethyl-substituted tetraethylene glycol. Treatment of dimethyl 4-methoxy-5-methyl-2,6-pyrimidinedicarboxylate 4 with the diamine derivative of chiral dibenzyl-substituted tetraethylene glycol gave the chiral dibenzyl-substituted pyrimidino-crown diamide 2. Starting 4-methoxy-5-methyl-2, 6-pyrimidinedimethanol 11 was prepared by a six step process from acetamidine hydrochloride and diethyl oxalpropionate.
