An efficient and transition-metal-free strategy for the synthesis of 3-keto-isoquinolines in one pot has been developed from the easily accessible 2-(formylphenyl)acrylates and phenacyl azides. Various substituted aldehydes and phenacyl azides were successfully employed in this transformation to furnish a variety 3-keto-isoquinolines in very good yields. A number of controlled experiments were conducted
Here in the present manuscript, we report our observation of an unprecedented stereoselective synthesis of 2H-isoindolin-1,3-ylidenes from 2-(formylphenyl)acrylates and phenacylazide in the presence of piperidine. Unlike in our previous findings, in which we accessed 3-keto-isoquinolines from the same starting materials under slightly modified reaction conditions, this unexpected one-pot tandem reaction
在本手稿中,我们报告了我们在哌啶存在下从 2-(甲酰基苯基)丙烯酸酯和苯甲酰肼中前所未有的立体选择性合成 2 H -isoindolin-1,3-ylidenes的观察结果。与我们之前的发现不同,我们在稍加修改的反应条件下从相同的起始材料中提取 3-酮基异喹啉,这种意想不到的一锅串联反应提供了一种有效且简单的方法来获取各种高度官能化的乙基 ( Z ) -2-(( Z )-3-(2-oxo-2-arylethylidene)-2,3-dihydro-1 H -benzo[ e ]isoindol-1-ylidene)-醋酸盐,产率非常好(高达91%)。本方法与多种官能团兼容。

A method for the synthesis of 2-aroyl-5-aryl-pyrroles using phenacyl azide and α,β-unsaturatedaldehyde at room temperature has been developed. High yield, atom economy and requirement of economic substrates, reagents and organocatalyst as well as non-involvement of cryogenic or very high temperature and inert or anhydrous conditions make this protocol a sustainable synthetic approach towards the synthesis
