Efficient procedures for the synthesis of 21-24- and 28-31-membered macrocyclic azino diesters and dihydrazido diesters were developed starting from L-menthol, Delta(3)-carene, (+)-alpha-pinene, tetrahydropyran, and 4-methyltetrahydropyran. The key steps in these syntheses were consecutive [2 + 1]- and [1 + 1]-condensations. The 31-membered dihydrazido diester exhibited strong antibacterial activity.
