ChemInform Abstract: A Facile Synthesis of a Sterically Congested Amide: A Convenient Method of Steroidal 17β-Amide Synthesis from 17β-Carboxylic Acid and a Hindered Amine with 2,4,6-Triisopropylbenzenesulfonyl Chloride as a Condensing Reagent.congested amide...
synthesis of these homochiral amides from racemic precursors is challenging using existing chemistries. The synthesis of the corresponding chiral carboxylic acid, required for a traditional amide coupling, can also involve multi-step synthesis using toxic and expensive transition-metals, tailored ligands ...
