Analysis of NMR Spectral Data of Structural Analogs of Ponasterone A and 9α,20-Dihydroxyecdysone with an Isoxazoline Ring in the Side Chain
Abstract
The signals of the hydrogen and carbon atoms nuclei of isoxazolinyl steroids, i.e., structural analogs of ponasterone A and 9α,20-dihydroxyecdysone, were assigned by two-dimensional NMR spectroscopy. The characteristic features of neighboring functional groups affecting the chemical shift of carbon and hydrogen atoms in the NMR spectra were revealed. Some data on the spectral characteristics of the previously described compounds were refined.
