“…A number of methods to synthesise hydantoins exist. [8,9] Treatment of α-amino acids, nitriles or amides with alkali cyanates is used mainly for the preparation of hydantoins with substituents at their C-5 positions, but also for N 1 -substituted hydantoins. Treatment of free α-amino acids, esters or nitriles with isocyanates is valuable when hydantoins substituted at their N-3 positions are desired.…”

“…É digno de nota que a hidantoína tem causado um grande impacto na indústria farmacêutica, visto que vá- ). Além das importantes atividades biológicas apresentadas por moléculas derivadas da hidantoína, vários outros aspectos relevantes acerca dessas substâncias têm sido abordados na literatura, cujo foco é dirigido para temas de grande interesse como a reatividade do anel imidazolidínico, a aplicação de novas metodologias de sín-tese, 11 a caracterização estrutural dos compostos, ou ainda, temas relacionados a ensaios biológicos e estudos de relação quantitativa estrutura-atividade -QSAR -Quantitative Structure Activity Relationships. 12 Tais estudos podem ser melhor apreciados graficamente (Figura 6), onde se observa o número de publicações no período de 1945-2006, obtido com a ferramenta de busca da internet da "Web of Science" com a base de dados "ISI Web of Knowledge" (utilizando as palavras chaves "imidazolidin* dione" e "hydantoin*" separadas pelo operador booleano "or" e o banco de dados "SCI-EXPANDED".…”
