Both the chiral centers of the diamine unit are essential, while the thiourea hydrogen originating from the amine and the amide hydrogen play a predominant role for the catalyst efficiency. 8 pp. LOMv1.0 creator LOMv1.0 Scientific Coordinator LOMv1.0 Project Executing Organisation 2012-05-30 Digital Library of the Operational Programme "Education and Lifelong Learning" abstract types Text Tripeptide-Like prolinamide thioureas Diphenylethylenediamine Thiourea hydrogen Amide hydrogen http://pubs.rsc.org/en/Content/ArticleLanding/2012/OB/c2ob25693b#!divAbstract 545962 application/pdf http://repository.edulll.gr/edulll/bitstream/10795/3010/2/3010_1.72_%ce%94%ce%97%ce%9c_30_7_12.pdf This article is part of themed collection Organocatalysis of Royal Society of Chemistry (RSC) URI http://hdl.handle.net/10795/3010 LOMv1.0creator 2016-05-05T07:58:22Z LOMv1.0validator 2016-05-05T07:58:22Z LOMv1.0 gre no no Copyright EYD-EPEDBM (Operational Programme "Education and Lifelong Learning")
