A process for producing a β-hydroxyester by reacting an epoxide, an alcohol and carbon monoxide in the presence of a cobalt carbonyl compound as catalyst,
which is characterized in using as co-catalyst, a pyridine derivative having an amino substituent of formula (1),
wherein R
1
and R
2
are independently hydrogen, formyl, acyl, alkoxycarbonyl, substituted or unsubstituted alkyl, substituted or unsubstituted aralkyl, substituted or unsubstituted aryl, or R
1
and R
2
may be taken together with the adjacent nitrogen atom to form a ring, and n is an integer of 1 or 2.
一种生产β-羟基酯的方法,包括在钴羰基化合物的催化下,通过反应环氧化物、醇和一氧化碳来实现,其特征在于使用一种具有式(1)中氨基取代基的吡啶衍生物作为共催化剂,其中R1和R2独立地是氢、甲酰、酰基、烷氧基羰基、取代或未取代的烷基、取代或未取代的芳基烷基、取代或未取代的芳基,或R1和R2可以与相邻的氮原子一起形成环,n是1或2的整数。
