Preparation of γ-lactams 2a-h and 4a-h as part of a bi-or tri-cycle system in a one-pot Ugi-4-centre-3-component reaction (U-4C-3CR). A 3-keto or aldo acid was used as bifunctional educt. The application of C-protected amino acids as amine components enables an intramolecular condensation forming 2,6-piperazinediones 5a-h, connected to the γ-lactam system (1,4-diazabicyclo[4.3.0]nonane-3,5,9-triones)

A new efficient synthesis of isoquinoline-1,3(2H,4H)-diones or isoindolin-1-ones via sequential Ugi-4CR or Ugi-3CR/cyclization reaction was developed. α-Acylamino amides 5, obtained from Ugi-4CR of methyl 2-formylbenzoate, amines, isocyanates and acids, cyclized to give isoquinoline-1,3(2H,4H)-diones 6 in good yields in the presence of catalytic amount of sodium ethoxide. Ugi-3CR of methyl 2-formylbenzoate
通过顺序的Ugi-4CR或Ugi-3CR /环化反应,开发了一种新的高效合成异喹啉-1,3(2 H,4 H)-二酮或异吲哚啉-1-酮的方法。由Ugi-4CR的2-甲酰基苯甲酸甲酯,胺,异氰酸酯和酸获得的α-酰基氨基酰胺5,在催化量的存在下,以高收率环化生成异喹啉-1,3(2 H,4 H)-二酮6乙醇钠。在催化量的H 3 PO 4存在下,2-甲酰基苯甲酸甲酯,胺和异氰酸酯的Ugi-3CR直接以一锅法产生异吲哚啉-1-酮7。
