Acyloxylactonisations mediated by lead tetracarboxylates
摘要:
The reaction of lead(IV) tetracarboxylates with carboxylic acids containing unsaturated side chains has been found to give acyloxy lactone products in a diastereoselective process; the reaction can be extended to lead(IV) tetrazolates to give the analogous outcome. Mechanistic implications of these results are discussed. (C) 2009 Elsevier Ltd. All rights reserved.
