Synthesis of new pyrrolidine-based organocatalysts and study of their use in the asymmetric Michael addition of aldehydes to nitroolefins 2017 Access copy available to the general public Unrestricted New pyrrolidine-based organocatalysts with a bulky substituent at C2 were synthesized from chiral imines derived from (R)-glyceraldehyde acetonide by diastereoselective allylation followed by a sequential hydrozirconation/iodination reaction. The new compounds were found to be effective organocatalysts for the Michael addition of aldehydes to nitroolefins and enantioselectivities up to 85% ee were achieved. info:eu-repo/grantAgreement/ES/DGA/GAE-102 info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 2.33 2017 CHEMISTRY, ORGANIC 25 / 57 = 0.439 2017 Q2 T2 0.929 2017 Organic Chemistry 2017 Q1 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Badorrey, R.
