Abstract
A mild and efficient procedure is described for the synthesis of amine-substituted diazoacetoacetates by the addition of ethyl 3-(tert-butyldimethylsilanoxy)-2-diazobut-3-enoate to aldimines catalysed by MgI2 etherate (MgI2•(OEt2)n) in MeCN. The reaction produces good to excellent yield at room temperature.
