reaction of ketones with organoboronic esters was developed. In this reaction, ketones possessing a pyridine-directing group directly functions as an alkenyl electrophile for coupling with organoboronates in the presence of pyrrolidine and a ruthenium catalyst. This reaction proceeds via the catalytic cleavage of the alkenyl carbon–nitrogen bond in the enamines generated in situ from ketones with pyrrolidine
开发了一种钌催化的酮与有机硼酸酯的交叉偶联反应。在该反应中,具有吡啶导向基团的酮在吡咯烷和钌催化剂存在下直接充当烯基亲电试剂,与有机硼酸酯偶联。该反应通过用吡咯烷、苄胺或异吲哚啉催化裂解由酮原位生成的烯胺中的烯基碳氮键进行。
