Conformational change in a urea catalyst induced by sodium cation and its effect on enantioselectivity of a Friedel-Crafts reaction

Chittoory, Arjun K.; Kumari, Gayatri; Mohapatra, Sudip; Kundu, Partha P.; Maji, Tapas K.; Narayana, Chandrabhas; Rajaram, Sridhar (Pergamon-Elsevier Science Ltd, 2014)

While developing bis-camphorsulfonyl urea as a hydrogen-bonding catalysts, we discovered that the native conformation of the catalyst is unsuitable for inducing enantioselectivity. By complexing the catalyst with weakly ...
Raman, IR and DFT studies of mechanism of sodium binding to urea catalyst

Kundu, Partha P.; Kumari, Gayatri; Chittoory, Arjun K.; Rajaram, Sridhar; Narayana, Chandrabhas (Elsevier Science Bv, 2015)

Bis-camphorsulfonyl urea, a newly developed hydrogen bonding catalyst, was evaluated in an enantioselective Friedel Crafts reaction. We observed that complexation of the sulfonyl urea with a sodium cation enhanced the ...
