众所周知,评价一个反应和合成的好坏,最常见的标准是收率和选择性(化学,区域,非对映和对映选择性)。16年前,P.T.Anastas和J.C.Warner首次定义了绿色化学。而“绿色标准”主要是从效率和环境等角度考虑的,就是三大经济性:原子经济性(atom economy),步骤经济性(step economy)和氧化还原经济性(redox economy)。这对合成提出了更高的要求,也为有志于合成的化学家指明了努力 It is well-known that the most common criteria for evaluating a reaction and its synthesis are yield and selectivity (chemical, regional, diastereomeric, and enantioselective). 16 years ago, P.T. Anastas and J.C. Warner first defined green chemistry. The “green standard” is mainly based on efficiency and environment. Three major economies are the atom economy, the step economy and the redox economy. This put forward higher requirements for the synthesis, but also pointed to the chemists interested in the synthesis of efforts
