1、The forcus of this thesis is on the[4+2]reactions of N-acyliminium cations with olefins and the synthesis of pyrrolo-and pyrrolidino[1，2-a]quinolin-1-ones.(1)The[4+2]reactions of N-acyliminium cations，produced from 5-hyd

2、roxy -1-arylpyrrol-2-ones or 5-hydroxy-1-arylpyrrolidin-2-ones in the presence of BF3·OEt2 with olefins has been studied.A flew method for the synthesis of pyrrolo[1，2-a]quinolinl-ones or pyrrolidino[1，2-a]quinolinl-one

3、s has been developed in moderate to good yields at ambient temperature.(2)The enantioseletive synthesis of the pyrrolidino[1,2-a]quinolin 1-ones and starting from L-malic acid and L-tartaric acid has been tried.(3)The co
