Poly(methylhydrosiloxane)-supported chiral imidazolinones: new versatile, highly efficient and recyclable organocatalysts for stereoselective Diels-Alder cycloaddition reactions / S. Guizzetti, M. Benaglia, J.S. Siegel. - In: CHEMICAL COMMUNICATIONS. - ISSN 1359-7345. - 48:26(2012), pp. 3188-3190.
Abstract:
Poly(methylhydrosiloxane) (PMHS) supported organic catalysts promoted the Diels–Alder reaction of dienes with α,β-unsaturated aldehydes, also in pure water, in yields and enantiomeric excesses comparable to those observed with the non-supported catalysts (up to 93% ee). Recycling of the catalysts was performed with no loss of enantioselectivity for at least five reaction cycles.
