Abstract

Results 1. Allylation of &Keto Esters and Malonates. At first allylation of methyl 2-methyl-3- oxopentanoate (1 1) with various allylic compounds was carried out in order to compare the reactivity of allylic compounds using palladium complexes combined with PPh, as the catalyst. As shown in Table I, reaction of diallyl carbonate (12) proceeded rapidly in 10 min without addition of a base at room temperature to give the allylated product 13 in nearly ...
