摘要
Efficient syntheses of two potentially useful optically active macroheterocycles with esters and dihydrazides of 2,6-pyridinedicarboxylic and adipic acids starting from available natural L-menthol and passing through intermediate 8-hydroxy-2,6R-dimethyloctan-3-one were developed. The key steps were [2 + 1]-reaction of the last with 2,6-pyridinedicarboxylic acid chloride and [1 + 1]-condensation of the resulting alpha,omega-diketodiester with 2,6-pyridinedicarboxylic- and adipic-acid dihydrazides. The structures were confirmed using IR and NMR spectroscopy and LC-MS.
