A Direct Transformation of Aryl Aldehydes to Benzyl Iodides Via Reductive Iodination
Ruso, Jayaraman Sembian,Rajendiran, Nagappan,Kumaran, Rajendran Senthil Korean Chemical Society 2014 대한화학회지 Vol.58 No.1
A facile transformation of aryl aldehydes to benzyl iodides through one-pot reductive iodination is reported. This protocol displays remarkable functional group tolerance and the title compound was obtained in good to excellent yield.
Antimicrobial Activities of Novel 3-Substituted [1,2,4] Triazolo[4,3-b]pyridazines Derivatives
Ruso, Jayaraman Sembian,Rajendiran, Nagappan,Srinivas, Chowdappa,Murthy, Konappa Narasimha,Soumya, Krishnamurthy Korean Chemical Society 2014 대한화학회지 Vol.58 No.4
A noval derivatives of 3-substituted[1,2,4]triazolo[4,3-b]pyridazine (4a-4o) and 7,8,9,10-tetrahydrobenzo[4,5] thieno[2,3-d][1,2,4]triazolo[4,3-b]pyridazine (7a-7l) is prepared by the reaction of heteroaryl hydrazone from the aldehyde and pyridazinohydrazine derivative, followed by subjecting the intermediate directly to oxidative cyclization employing the mixture of $Me_4NBr$ and Oxone. These derivatives were subjected to preliminary antimicrobial activities against microorganism. All these compounds exhibit good to moderate activity.
Ruso, Jayaraman Sembian,Nagappan, Rajendiran,Kumaran, Rajendran Senthil Korean Chemical Society 2013 대한화학회지 Vol.57 No.5
A facile one-pot syhthesis of 3-substituted triazolopyridazine and thieno-triazolopyridazine derivatives is described. This protocol involves the preparation of heteroaryl hydrazone from the aldehyde and pyridazinohydrazine derivative followed by subjecting the intermediate directly to oxidative cyclization to assemble the desired 1,2,4-triazloe moiety by employing the mixture of Me4NBr and oxone. This condition is efficient and is able to tolerate wide range of functional groups.
