Description
A new set of phosphorus-containing chiral ligands has been synthesized and used with silver(I) for the catalytic asymmetric 1 3-dipolar cycloaddition reaction of azomethine ylides One of these ligands (POFAM6) was found to produce an effective catalyst for the asymmetric 1 3 dipolar cycloaddition reaction of azomethine ylides with electron deficient dipolarophiles to form pyrrolidines in up to 97% yield and 89% (C) 2010 Elsevier Ltd All rights reserved
