In acidic media o-phenylenediamine and 2-oxoacids react to yield quinoxaline derivatives. On derivatization in pyridine with silylating reagents quinoxalinol-O-TMS ethers or O-TMS-ether-TMS-esters are formed exclusively as shown by gas chromatography infrared spectrometry and gas chromatography mass
The mechanisms leading to the major ions in the mass spectra of the trimethylsilyl derivatives of cis-and trans-hexahydrocannabinol, five monohydroxy analogues, eight dihydroxy analogues, and two carboxylic acid derivatives were investigated with the aid of deuterium labelling and high resolution ma
