Baker's yeast reduction of methyl substituted γ-and δ-keto acids1–6proceeds in a mode depending upon subtle substrate structural modifications; it affords γ-lactones of modest ee and de values and highly functionalized, enantiomerically pure δ-lactones, such as13from which cis-(+)-rose oxide23ahas been prepared.
贝克酵母还原甲基取代的γ-和δ-酮酸1-6的方式取决于微妙的底物结构修饰。它提供具有适度的ee和de值的γ-内酯,以及高度官能化的对映体纯的δ-内酯,例如由13制得的顺-(+)-玫瑰氧化物23a 。
