Two Novel and Simple Approaches to "CD45 Protein Tyrosine Phosphatase Inhibitor' (Z)-Pulchellalactam and Derivatives
Résumé
Two novel routes to the naturally occurring CD45 protein tyrosine phosphatase inhibitor, (Z)-pulchellalactam, and its derivatives are reported in two steps starting from dienoic acids through electrophilic cyclisation. This methodology proceeds regio- and stereoselectively, and can be used to design a library of synthetic pulchellalactam analogues.
