A mild and general strategy for the synthesis of 2-substituted 4-amino-1,2,4,5-tetrahydro-2-benzazepine-3-ones is described. The seven-membered lactam is prepared by intramolecular amide bond formation from the intermediate amino acid, which is obtained either by reductive alkylation of a variety of amines with N-Boc,N-Me-ortho-formyl-Phe and Phth-ortho-formyl-Phe, or by reductive amination of a variety of aldehydes with N-Boc-ortho-aminomethyl-Phe.

2-取代的4-氨基-1,2,4,5-四氢-2-苯并ze庚因-3-酮的通用合成

描述了合成2-取代的4-氨基-1,2,4,5-四氢-2-苯并ze庚因-3-酮的温和且通用的策略。七元内酰胺是通过从中间氨基酸，它是由各种与胺的还原性烷基化得到的任一分子内形成酰胺键制备Ñ -Boc，Ñ -Me-邻-甲酰基Phe和Phth-邻-甲酰基-Phe，或通过将各种醛与N -Boc-邻-氨基甲基-Phe还原胺化而制得。
