The main synthetic approach was planned to start from the formylated pyrrole (i) in order to obtain the compound (ii) as a precursor for the synthesis of chlorins. Subsequent oxidation was also planned to give the corresponding benzochlorins (iii) (Scheme iv)... continua no texto / Neste trabalho foram realizados alguns estudos visando a síntese de novos derivados do tipo benzoclorinas contendo bandas de absorção entre as regiões do visível e infravermelho próximo. A principal abordagem sintética adotada consistiu em se utilizar o pirrol formilado (i), o qual seria empregado na síntese do composto (ii), possibilitando, assim, a formação de clorinas devidamente preparadas para oxidação e obtenção dos compostos desejados (iii) (Esquema i)... continua no texto
