Abstract
Patente de Invenção: <B>"PROCESSO PARA PRODUçãO DE DERIVADOS DE PURINA E INTERMEDIáRIOS PARA OS MESMOS"<D>. Processo para produção de um composto de fórmula (I), onde X é H, OH ou halo; e R~ 1~ e R~ 2~ são selecionados, independentemente dentre C~ 1-12~ alquila, arila, C~ 1-12~ alquilarila, C~ 1-12~ alquilsilila, arilsilila e C~ 1-12~ alquilarilsilila ou R~ 1~ e R~ 2~ são considerados juntos para formar um acetal ou cetal cíclico; cujo processo compreende reagir um composto de fórmula (II) com um composto de fórmula (III), onde Y é um grupo de partida, na presença de um catalisador de paládio (0) e de um ligante. O processo propicia um novo método de produção de famciclovir e penciclovir.
