The invention is aimed at a compound of formula (I) wherein n is 0, 1 or 2, R1 is a linear or branched alkyl group, R2 is selected from a substituted or non substituted alkyl group, substituted or non substituted aryl group, substituted or non substituted aralkyl group, substituted or non substituted heterocyclyl group, or a substituted or non substituted heterocyclylalkyl group. Another object of the invention is a process for obtaining these compounds from the corresponding compound with a hydroxy group in position 4 by means of reacting with a sulfonamide in the presence of a phosphine and a dialkyl azadicarboxylate. The deprotection of the compound of formula (I) gives rise to the corresponding amine. The intermediate and the processes described are very useful in the synthesis of pharmaceutical products.
本发明旨在提供一种化合物,其
化学式为(I),其中n为0、1或2,R1为线性或支链烷基,R2选择自取代或非取代烷基,取代或非取代芳基,取代或非取代芳基烷基,取代或非取代杂环基,或取代或非取代杂环基烷基。本发明的另一个目的是提供一种从位置4带有羟基的相应化合物经过在
