The use of the Pd(dba)12/dpe catalytic system in allylic alkylation allows sodium dimethyl malonate to react with allylicacetates at room temperature. According to this procedure, a novel synthesis of allylicsubstituted cyclopentadienes is described through the use of cyclopentadienide anion as a nucleophile.
2-Substituted 7-cycloalkenyl carbonates are suitable substrates for asymmetric allylic substitution reaction using 9-PBN coordinated palladium, producing the allylic substituted products with high enantiomeric excess. (C) 2001 Elsevier Science Ltd. All rights reserved.
