A process is disclosed for the production of alkyl-5-substituted-3-furoate compounds of the general formula:
in which R1 is phenyl or an unsubstituted or substituted aryl which substituent will not adversely affect the reaction and R2 is a lower alkyl having 1 to 6 carbon atoms employing alkyl-4-oxo-5-substituted-pentanoate as a starting material.
本发明公开了一种生产通式为 5-取代-3-糠酸烷基化合物的工艺:
其中 R1 是苯基或未取代或取代的芳基,取代基不会对反应产生不利影响;R2 是具有 1 至 6 个碳原子的低级烷基,以 4-氧代-5-取代戊酸烷基酯为起始原料。
