- W2007905906 abstract "A number of methods of preparation were studied in an attempt to synthesize 5-vinyl-hydantoin using acrolein as a starting material. There were three possible routes: 1) the thermal decomposition of 5-(9,10-dihydroanthracene-9,10-endo-α, β-ethyl)-hydantoin at 400°C; 2) that of 5-(2-acetoxyethyl)-hydantoin and 3) the elimination reaction of dimethyl 2-(5-hydantoin)-ethyl sulfonium iodide in dimethyl sulfoxide by potassium t-butoxide. However, all the reactions gave 5-ethylidene-hydantoin as the product instead of 5-vinyl-hydantoin. An extreme ease of isomerization from 5-vinyl-hydantoin to 5-ethylidene-hydantoin was caused by the highly stable structure of the latter compound. The strong resonance stabilization of 5-ethylidene-hydantoin was observed in the ultraviolet spectrum. 5-Methyl-5-vinyl-hydantoin, which has no migrating hydrogen, could not be obtained from the 5-methyl derivatives of the above compounds." @default.
