Cyrene as a bio-alternative dipolar aprotic solvent: a waste minimizing and molar efficient protocol for the synthesis of amides from acid chlorides and primary amines in the bio-available solvent Cyrene is disclosed. This protocol removed the use of toxic solvents, such as dimethylformamide and dichloromethane. A simple aqueous work-up procedure for the removal of the high boiling solvent Cyrene resulted in up to a 55-fold increase in molar efficiency (Mol E.%) versus standard operating procedures. In order to rapidly compare the molar efficiency of this process against other methodologies an Excel based Mol. E% calculator was developed that automates many of the calculations. An investigation into the hydration of Cyrene found that it readily hydrates to form a geminal diol in the presence of water and that this process is exothermic.
Rhodium-Catalyzed Synthesis of Amides from Functionalized Blocked Isocyanates
Beauchemin, André M.,Derasp, Joshua S.
, p. 8104 - 8109 (2019/08/26)
Isocyanates are useful building blocks for the synthesis of amides, although their widespread use has been limited by their high reactivity, which often results in poor functional group tolerance and a propensity to oligomerize. Herein, a rhodium-catalyzed synthesis of amides is described coupling boroxines with blocked (masked) isocyanates. The success of the reaction hinges on the ability to form both the isocyanate and the organorhodium intermediates in situ. Relying on masked isocyanate precursors and on the high reactivity of the organorhodium intermediate results in broad functional group tolerance, including protic nucleophilic groups such as amines, anilines, and alcohols.

experimental part, p. 899 - 902 (2010/05/03)
Dithiocarbamate and DBU-promoted amide bond formation under microwave condition has been reported. The versatility of this synthetic protocol has been demonstrated with various carboxylic acids and different dithiocarbamates. The products thus obtained ha
Hansch analysis of veratric acid derivatives as antimicrobial agents
Narasimhan, Balasubramanian,Ohlan, Sucheta,Ohlan, Ruchita,Judge, Vikramjeet,Narang, Rakesh
experimental part, p. 689 - 700 (2009/09/08)
The synthesis, characterization and antimicrobial evaluation of a new series of veratric acid derivatives are presented. Preliminary in vitro antimicrobial activity of the title compounds was assessed against a panel of microorganisms including Gram-positive and Gram-negative bacteria and fungi. Some of the veratric acid derivatives exhibited significant in vitro antimicrobial activity. QSAR investigation applied to find a correlation between different physicochemical parameters of the veratric acid derivatives and their antimicrobial activity indicated the importance of topological parameters in describing the antimicrobial activity.
