A method of synthesis is provided to obtain a range of UV absorbing compounds. The method broadly involves(a) the reduction of a glutarimide or its reaction with a carbon nucleophile; (b) when step (a) is a reduction, exposing the product of step (a) to an acidic environment to form a cyclic amide; (c) reducing the product of step (a) or step (b) to form a corresponding enamine; and subjecting the enamine product of step (c) to an acylation.
提供了一种合成方法,用于获得一系列UV吸收化合物。该方法广泛涉及(a)还原戊二酰亚胺或其与碳亲核试剂的反应;(b) 当步骤(a)是还原时,将步骤(a)的产物暴露在酸性环境中形成环酰胺;(c) 还原步骤(a)或步骤(b)的产物形成相应的烯胺;并将步骤(c)的烯胺产物置于酰化作用下。
