研究了碱式碳酸钴为催化剂, 碳酸银为氧化剂, 碳酸钠为碱, 1-萘胺衍生物与α-羰基羧酸的sp2碳氢键活化酰氧基化反应, 从而得到了相应的芳香酯类化合物. 各种取代的苯甲酰甲酸、萘甲酰甲酸及噻吩-2-甲酰甲酸均能以中等及以上的收率得到目标化合物. 此外, 当反应中使用氘代苯甲酰甲酸作为反应底物时, 反应仍可以以62%的产率得到同位素标记的芳香酯化产物.

The cobalt-catalyzed decarbonylative C(8)-acyloxylation of 1-naphthalamine derivatives with α-oxocarboxylic acids in the presence of Ag2CO3 and Na2CO3 was developed. Various substituted phenylglyoxylic acids, naphthalenylglyoxylic acid and 2-oxo-2-(thiophen-2-yl)acetic acid can be tolerated in this reaction, giving the desired products in moderate yields. In addition, when deuterated allyl glyoxylic acid is used, the yield of isotope labeled aromatic esterification product is 62%.

Key words: cobalt-catalyzed, C—H activation, 1-naphthylamide, α-oxocarboxylic acids, C(8)-acyloxylation
