No full textSintesi di solfossidi mediante ossidazione di tioeteri con acido nitrico catalizzata da Au(III) in condizioni di trasferimento di fase
No full textSynthesis of both enantiomers of 4-vinyl oxazolidin-2-one from a single precursor: D-isoascorbic acid
Full text linkA convenient synthesis of (S)- and (R)-4-vinyl oxazolidin-2-one
from the same inexpensive starting material, D-isoascorbic acid, is described. The two compounds were obtained in 44% and 38% yield, respectively, by operationally simple steps. This approach is a suitable alternative to the literature methods and enhances the synthetic utility of these intermediates
