pyridine-2,6-dicarboxylic and adipic acidester and hydrazide fragments starting from tetrahydropyran (commercial petrochemical product) through intermediate 8-hydroxyoctan-2-one. The key stages were [2+1]-condensation of the latter with pyridine-2,6-dicarboxylic and adipic acid chlorides and [1+1]-condensation of the resulting α,ω-diketo diesters with dihydrazides derivedfrom the same diacids.

The synthesis of two potentially useful optically active 23- and 30-membered macrolides containing a 1,2-diol system and dihydrazide fragments was developed starting from tetrahydropyran. It was based on [1+1]-condensation of 7-oxooctyl-7-oxooctanoate and bis(7-oxooctyl)hexanedioate with L-(+)-tartaricacid hydrazide.

useful bicyclic 26- and 33-membered macrolides containing 1,3-dioxolane and hydrazide fragments was developed starting from tetrahydropyran via a [1+1]-condensation of 7′-oxooctyl-7-oxooctanoate and bis(7-oxooctyl)hexanedioate with hydrazide of L-(+)-tartaric acid acetonide derivative.

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.
