Description
A new route to naphth [1,2-d] oxazoles form naphthoquinones and primary alkyl amines is described. The reaction probably proceeds through the formation of an intermediate tautomeric 1,2-naphthoquinone of an intermediate tautomeric 1,2-naphthoquinone structure of lapachol. The reaction of benzylamine with β-lapachone also gives rise to functionalized oxazole. Nuclear magnetic resonance and infrared, ultraviolet and mass spectroscopy analysis are presented. (author)
Abstract (Portuguese)
Neste trabalho e descrito uma nova rota sintetica para oxazois substituidos, a partir de quinonas e alquilaminas. Mecanisticamente, e postulada a participacao de uma forma tautomerica do lapachol, do tipo 1,2-quinoidal. β-lapachona tambem forma oxazois substituidos. Apresentam-se analises de ressonancia magnetica nuclear e espectroscopia de infravermelho, ultra-violeta e de massa. (autor)Additional details
