Lutter, Ferdinand H. published the artcileFacile Conversion of Molecularly Complex (Hetero)aryl Carboxylic Acids into Alkynes for Accelerated SAR Exploration, Category: esters-buliding-blocks, the publication is Chemistry – A European Journal (2021), 27(60), 14816-14820, database is CAplus and MEDLINE.
Herein, a functional-group-tolerant and operationally simple decarbonylative alkynylation that allows the conversion of complex (hetero)aryl carboxylic acids into alkynes were reported. Furthermore, the utility of this method was demonstrated in the preparation of a triazolo analog of the com. drug moclobemide. Lastly, mechanistic investigations using labeled carboxylic acid derivatives clearly show the decarbonylative nature of this transformation.
