Follow that dream: By combining a reversible transesterification between benzylic alcohols and dialkyl oxalates with catalytic decarboxylation of the resulting esters, a regiospecific CC‐bond‐forming reaction to give α‐arylacetates was achieved. In the overall process, CO2 and a volatile alcohol are the only byproducts. Various α‐arylacetates were thus synthesized in high yields from easily accessible
遵循这个梦想:通过与所得到的酯的催化脱羧,一个区域专一Ç
苄醇和
草酸二烷基酯之间的酯交换反应的可逆结合 C-键形成反应,实现以得到α-arylacetates。在整个过程中,CO 2和挥发性醇是唯一的副产物。因此,在催化量的Pd(OAc)2,dppp和
DABCO的存在下,由易于获得的起始原料以高收率合成了各种α-芳基
乙酸酯(参见方案)。
