Hydantoin synthesis - University of Oxford.
Hydantoin, or glycolylurea, is a heterocyclic organic compound with the formula CH 2 C(O)NHC(O)NH. It is a colorless solid that arises from the reaction of glycolic acid and urea.It is an oxidized derivative of imidazolidine.In a more general sense, hydantoins can refer to a groups and a class of compounds with the same ring structure as the parent. For example, phenytoin (mentioned below) has.Why Did You Join A Sorority. Why You Should Join The National Guard True soldiers of hope do not do what they do for glory, fame, or to be superior over others, they do what they do because of the love in their heart and soul and for the greater good of mankind. Any real soldier can tell you this awe inspiring statement, as it is a reflection of their motivation, the element which compels them.This hydantoin is then converted into the hydantoin of phenylalanine, by reduction, and the amino-acid then obtained by hydrolysis with barium hydroxide.’ The various changes involved in these seven different methods of synthesis are represented by the formulas given on the follow- ing page.
The hydantoin moiety festooned with isoxazoline skeleton has been considered significant due to various medicinal and agrochemical applications. Park et al. reported the solid-phase synthesis of spiro heterocycles by coupling of Boc-protected cyclopentene carboxylic acid with Merrifield resin in the presence of 18-crown-6 to furnish a resin-bound ester.Hydantoin is an imidazolidine-2,4-dione.

Recently, we have reported a one-pot gallium(III) triflate-catalysed synthesis of hydantoins from aldehydes and ketones (shown below). This reaction has a good scope and can be conducted in a number of organic solvents. Future research will focus on improving this reaction and applying the methodology to the synthesis of related heterocycles.
