Use of the N–O Bonds in N-Mesyloxyamides and N-Mesyloxyimides To Gain Access to 5-Alkoxy-3,4-dialkyloxazol-2-ones and 3-Hetero-Substituted Succinimides: A Combined Experimental and Theoretical Study
The reactivity of N-mesyloxyamides and -imides with bases was studied based on the initial hypothesis of a possible [3,3]-rearrangement. While the intended α-sulfonyloxylation method could not be developed, the formation of valuable N-containing heterocyclic products was found. Treating N-mesyloxyamides with triethylamine gave fully substituted oxazolone products, which are masked α-amino acid derivatives
