A process for obtaining an amide of the general formula R—(CO)—NH—CH2—X involves contacting a nitrile of the general formula R—CN with:
a) an acid; and
c) an alkoxy-containing compound comprising at least one alkoxy functionality of the general formula —OCH2—X;
wherein R is hydrogen or an alkyl, cycloalkyl, alkenyl, cycloalkenyl, alkynyl, aryl, or heterocyclic substituent, which substituents can be substituted or unsubstituted; wherein X is hydrogen or a radical having the general formula —CHR1R2; and wherein R1 and R2 independently or collectively represent hydrogen or an alkyl, cycloalkyl, alkenyl, cycloalkenyl, alkynyl, aryl, or heterocyclic substituent, or any combination thereof, which substituents can be substituted or unsubstituted. Moreover, the inventive process can involve other similar reactions, for example, at least one nitrile can be reacted with a reagent comprising both (i) at least one suitable alkoxy functionality; and (ii) at least one suitable acid functionality.
获得通用公式R—(CO)—NH—CH2—X的酰胺的过程涉及将通用公式R—CN的腈与:a)酸;和c)至少含有一个通用公式—OCH2—X的烷氧基官能团的化合物接触;其中R是氢或烷基、环烷基、烯基、环烯基、炔基、芳基或杂环取代基,这些取代基可以是取代或未取代的;其中X是氢或具有通用公式—CHR1R2的基团;其中R1和R2独立或共同表示氢或烷基、环烷基、烯基、环烯基、炔基、芳基或杂环取代基,或任何这些取代基的组合,这些取代基可以是取代或未取代的。此外,创新的过程可以涉及其他类似的反应,例如,至少一个腈可以与包含(i)至少一个合适的烷氧基官能团;和(ii)至少一个合适的酸官能团的试剂发生反应。
