A process for preparing O-carbamoyl aminoalcohols represented by Formula(I) wherein: n is an integer from 0 and 5; R1, R2, R3 and R4 are individually selected from the group consisting of hydrogen, alkyl, cycloalkyl, substituted or unsubstituted aryl and arylalkyl the aryl portion of which may be unsubstituted or substituted; R5 and R6 are individually selected from the group consisting of hydrogen, alkyl or arylalkyl the aryl portion of which may be unsubstituted or substituted; or R1 and R5 together with the carbon and nitrogen to which they are attached may form an unfused or fused heterocyclic ring having from 4 to 10 members, comprising reacting an aminoalcohol represented by Formula (II) wherein n, R1, R2, R3, R4, R5 and R6 are as defined; with a cyanate and an excess of an acid in an organic solvent medium.
一种制备式(I)所表示的O-氨基醇酰胺类化合物的方法,其中:n为0到5的整数;R1、R2、R3和R4分别选自氢、烷基、环烷基、取代或未取代芳基和芳基烷基,其中芳基部分可以是未取代或取代的;R5和R6分别选自氢、烷基或芳基烷基,其中芳基部分可以是未取代或取代的;或者R1和R5与它们所连接的碳和氮一起可以形成从4到10个成员的未融合或融合的杂环环;包括在有机溶剂介质中,通过反应式(II)所表示的氨基醇,其中n,R1,R2,R3,R4,R5和R6如定义所述;与氰酸酯和过量酸反应。
