5-ARYLIDENE-2-THIO-4-OXAZOLIDINONES IN HYDROXY- AND AMINOMETHYLATION REACTIONS
Shenberg, N. A.,Ginak, A. I.,Ramsh, S. M.,Khrabrova, E. S.
, p. 91 - 93 (1989)
Hydroxymethylation and aminomethylation reactions of 5-arylidene-2-thio-4-oxazolidinones lead to the formation of substitution products at the ring nitrogen atom; this has been attributed to thermodynamic reaction control.
