We hereby report Ru(ii)-catalyzed C(sp2)-H allenylation of N-tosylbenzamides to access multi-substituted allenylamides. Furthermore, the allenylamides were converted to the corresponding isoquinolone derivatives via base mediated annulation. The current protocol features low catalyst loading, mild reaction conditions, high functional group compatibility and desired scalability. The unique functionality of the afforded allenes allowed further transformations to expand the practicality of the protocol. This journal is

Paragraph 0104-0110; 0121, (2021/09/21)
The present invention relates to a novel amidation process. To the present invention, an active N -center radical activated by light irradiation can be utilized to provide a selective amidation method. In addition, the present invention can provide an amide compound derived from an aldehyde having a functional group of various aspects, and is expected to be applicable to various technical fields.
