英文摘要 | The K^2CO^3 (1O mol %)-catalyzed l .4-addition reaction of diethyl malonate with various substitu l .2-allenic ketones leading to polyfunctionalized β.γ-unsaturated enones 3 or 4 was studied. N 3- unsubstituted l-substituted- l ,2-allenyl ketones. The highly selective formation ofβ.γ-unsatura enones 4 was obsewedi with l.2-allenyl ketones bearing one or two 3-substituents in the alle group. Only β.γ-unsaturated enones 3 with an unmigrated carbon-carbon double bond w produced; with 3-monosubstituted- l ,2-allenyl ketones Z-β.γ-unsaturated enones 3 were formed w excellent stereoselectivity (E:Z > 96:4); with propadienyl keLones. Mixtures of β.γ-unsatura enones 3 and 4 were formed. Α-Pyrone derivatives were synthesized via the K^2CO^3-catalyzec -promoted reaction of l .2-allenic ketones with dieLhyl malonate via a sequential Michael additic carbon-carbon double bond migration-lactonization process. |
