  NH₂ As a Directing Group: From the Cyclopalladation of Amino Esters to the Preparation of Benzolactams by Palladium(II)-Catalyzed Carbonylation of N-Unprotected Arylethylamines

  摘要：

  An unusual NH2-directed Pd(II)-catalyzed carbonylation of quaternary aromatic alpha-amino esters to yield benzolactams has been developed. The steric hindrance around the amino group is pivotal for the success of the process. The stoichiometric cyclometalation of a variety amino esters has been studied in order to evaluate the influence of the different variables (size of the metallacycle, aromatic ring substituents, and steric bulk) in the process, and a complete kinetico-mechanistic study of the cyclopalladation process has been carried out. The experimental results indicate that the full substitution of the carbon in the alpha position of the amino esters plays an important role in their cyclopalladation reaction. The reaction shows a strong bias toward six-membered lactams over the five-membered analogues, which can be explained by a greater reactivity of the six-membered palladacycles.

  An unprecedented NH2-directed Pd(II)-catalytic carbonylation of quaternary aromatic α-amino esters to yield 6-membered benzolactams has been developed. The reaction shows a strong bias to 6-membered lactams over 5-membered ones. The steric hindrance around the amino group seems to be pivotal for the success of the process.

  Tetrahydro-3-benzazepines and tetrahydroiso-quinolines are synthesized in one,step from allenes and phenylethylamines or benzylamines,Mechanitically, it is assumed that activation of an aromatic ring with Pd(II) occurs, directed by the primary amine, leading to the formation of a palladacycltinto which'ari, allene then undergoes insertion. The resulting, pi-allyl intermediate cyclizes to the products by aniptramolecular allylic alkylation. The process is particularly useful with 2,3-butadienoates and amines having a quaternary carbon at the alpha-position.
