摘要

Eleven new chiral macrocycles (1-1 1, see Figure 1) of the pyridino-18-crown-6 type have been prepared. Nine diazapyridino-crown ligands contain two amide (1, R= benzyl; 4, R= phenyl), two N-methylamide (7, R= phenyl), two thionoamide (2, R= benzyl; 6, R= phenyl), two N-methylthionoamide (8, R= phenyl), two amine (3, R= benzyl; 6, R= phenyl), or two N- methylamine (9, R= phenyl) groups incorporated into the macroring. The appropriate ...
