摘要
The methoxime derivatives of N‐acyl prostaglandin E2 carboxamides (PG imides), when analyzed in the presence of excess N,O‐bis(trimethylsilyl)trifluoroacetamide by gas chromatography, were converted to nitriles and trimethylsilyl esters. For example, the methoximetrimethylsilyl (MO‐TMS) derivative of N‐acetyl PGE2 carboxamide was converted to the MO‐TMS derivative of 9‐keto‐11,15‐dihydroxy‐prost‐5,13‐dienonitrile and the MO‐TMS derivative of PGE2. The ratio of rearrangement products was found to be dependent upon the nature of the N‐acyl group, and the rearrangement apparently took place in the vapor phase after silylation of the imide moiety.
