(CO)4,the corresponding aniline derivatives were produced in 61-92% isolated yields.More impressively,a selective synthesis of cyclic amines such as pyrrolidines,piperidines and azepanes were conducted from levulinic acid,1,5-and 1,6-keto acids,respectively.The sequential procedure proceeded under ...
Carboazidation of alkenes and alkynes holds the promise to construct valuable molecules directly from chemical feedstock therefore is significantly important. Although a few examples have been developed, there are still some unsolved problems and lack of universal methods for carboazidation of both alk...
