Abstract
sínteses de furanos substituídos. é fornecido um método de preparação de um composto de fórmula ii: fórmula ii em que: r1 e r2 são independentemente selecionados a partir de -ch2or', -cho, -coor' e -h, desde que r1 e r2 não sejam ambos -h; e r' é selecionado a partir de ?h e c1-6 grupos hidrocarbila, a partir de um composto de fórmula i: fórmula i os compostos de fórmulas i e ii estando opcionalmente na forma de um sal. o método compreende a desidratação do composto de fórmula i a: um ph na faixa de 0 a 6 ou 8 a 11,5; e uma temperatura na faixa de 10 a 80°c. o método é particularmente útil para sintetizar furanos substituídos a partir de compostos derivados de açúcares.
