(HMe2SiCH2)2 has been utilized as a useful reagent for B(C6F5)3-catalyzed reduction–lactonization of keto acids to synthesize γ- and δ-lactones. The process led concisely to (–)-cis-whisky and (–)-cis-cognac lactones in respective overall yields of 32% and 36%.
(HMe2SiCH2)2 已被用作 B(C6F5)3 催化的酮酸还原-内酯化合成γ-和δ-内酯的有用试剂。该过程简明地导致 (-)-cis-whisky 和 (-)-cis-cognac 内酯的总产率分别为 32% 和 36%。
