, (2020/01/08)
A simple synthesis of 2-aroylindoles via palladium-catalyzed tandem oxidative annulation directly from α-amino ketones has been developed. In this transformation, two-step reaction including oxidation of α-amino aetones to generate imine intermediates and

Cp*Co(iii)-catalysed selective alkylation of directed C-H bonds of arenes and heteroarenes has been accomplished employing donor-acceptor carbenes, derived from α-diazocarbonyl compounds. The developed method allows ready access to various substituted α-(hetero)aryl-α-arylacetic acid derivatives in good to excellent yields. Synthetic utility was also shown through the synthesis of a substituted indole derivative, an anticancer agent.
A new approach to 1-substituted β-carbolines and isoquinolines utilizing tributyl[(Z)-2-ethoxyvinyl]stannane as a C-3,C-4 building block

Starting from readily available indole-2-carboxylic acids, 1-substituted β-carbolines (among them the alkaloids harmane and isoharmine) are readily obtained via the corresponding 2-acylindoles, bromination at C-3, followed by a one-pot Stille cross-coupling with tributyl[(Z)-2-ethoxyvinyl]stannane, and ring closure with ammonium acetate. 1-Substituted isoquinolines are available in an analogous manner starting from 2-bromobenzoic acid.
