Asymmetric 1,3-dipolar cycloaddition reactions between enals and nitrones catalysed by half-sandwich rhodium or iridium diphosphane complexes 2015 Access copy available to the general public Unrestricted The aqua complexes ¿(¿5-C5Me5)M¿PP*)¿H2O)]¿SbF6]2 (M = Rh, Ir; PP* = chiral diphosphane) have been tested as catalysts for the asymmetric 1,3-dipolar cycloaddition of nitrones to a,ß-unsaturated aldehydes. Quantitative conversions with very high regioselectivity, perfect endo selectivity and excellent enantioselectivity (up to 99% ee) were achieved. The stereochemical outcome was analyzed on the basis of the stereoelectronic properties of the intermediate enal complexes of the formula ¿(¿5-C5Me5)M¿PP*)¿enal)]¿SbF6]2. info:eu-repo/grantAgreement/ES/MINECO/CTQ2012-32095 info:eu-repo/semantics/openAccess All rights reserved http://www.europeana.eu/rights/rr-f/ 5.287 2015 CHEMISTRY, PHYSICAL 28 / 144 = 0.194 2015 Q1 T1 1.804 2015 Catalysis 2015 Q1 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion (orcid)0000-0002-6160-3046 Viguri, F.
