Abstract

Using this new process, various unsubstituted β-ketoesters can be prepared rapidly (Table 1, entries 1–5). We were pleased to discover that the substrate scope for the reaction accommodates three different diazo esters, (entries 1, 2 and 5) and both alkyl and aryl acylsilanes (entries 3 and 4). A novel aspect of this new process is the ability to utilize the dianion equivalent in carbon–carbon bond forming reactions. For example, the addition of MeI to the reaction in ...
