a 1 3 Amino Group migration route to form acrylamidines
ChemInform, 2014Co-Authors: Dinesh Pratapsinh Chauhan, Sreejith Jayasree Varma, Arjun Vijeta, Pallavi Banerjee, Pinaki TalukdarAbstract:A novel route for the synthesis of acrylamidines by Cu-catalyzed addition of tosylazide to 1-Aminopropines and subsequent intramolecular addition of nucleophiles to ketenimines with 1,3-Amino Group migration is presented.

a 1 3 Amino Group migration route to form acrylamidines
Chemical Communications, 2014Co-Authors: Dinesh Pratapsinh Chauhan, Sreejith Jayasree Varma, Arjun Vijeta, Pallavi Banerjee, Pinaki TalukdarAbstract:A novel 1,3-Amino Group migration strategy for the synthesis of acrylamidines is presented. Cu(I) catalyzed reaction of N,N-disubstituted propargylamine with tosylazide generates a highly reactive ketenimine intermediate which is trapped by a tethered Amino Group leading to the rearrangement reaction.

vinylic Amino Group activation a new and general strategy leading to functionalized fused heteroaromatics
ChemInform, 2013Co-Authors: Rajnikanth Sunke, Raju Adepu, Ravikumar Kapavarapu, Swetha Chintala, Chandana Lakshmi T Meda, Kishore V L ParsaAbstract:With a view to find novel inhibitors of phosphodiesterase 4 (PDE4), a series of tetracyclic heteroaromatics (IV) and (VII) is prepared by intramolecular cyclization of corresponding amines (III) and (VI).

lanthanide catalyzed reversible alkynyl exchange by carbon carbon single bond cleavage assisted by a secondary Amino Group
Angewandte Chemie, 2016Co-Authors: Yinlin Shao, Fangjun Zhang, Jie Zhang, Xigeng ZhouAbstract:Lanthanide-catalyzed alkynyl exchange through C−C single-bond cleavage assisted by a secondary Amino Group is reported. A lanthanide amido complex is proposed as a key intermediate, which undergoes unprecedented reversible β-alkynyl elimination followed by alkynyl exchange and imine reinsertion. The in situ homo- and cross-dimerization of the liberated alkyne can serve as an additional driving force to shift the metathesis equilibrium to completion. This reaction is formally complementary to conventional alkyne metathesis and allows the selective transformation of internal propargylamines into those bearing different substituents on the alkyne terminus in moderate to excellent yields under operationally simple reaction conditions.

fecl3 catalyzed regioselective c alkylation of indolylnitroalkenes with Amino Group substituted arenes
Journal of Organic Chemistry, 2014Co-Authors: Manoj R Zanwar, Veerababurao Kavala, Sachin D Gawande, Wenchang Huang, Hsiuni Huang, Chiu Hui HeAbstract:An efficient FeCl3 catalyzed protocol for the synthesis of Amino functionalized indolylnitroalkanes from easily available precursor indolylnitroalkenes and substituted amines has been developed. Regioselective C-alkylation in the presence of free Amino substituted arenes occurred. The scope of this methodology shows good functional Group tolerance, and further, this protocol was used to prepare indolylquinoline derivatives.
