| Abstract: | Lithiation (n-BuLi) of the (3′-methoxyphenyl) oxazoline (2a) occurs specifically at C2′ and, following carboxylation (CO2/13CO2) and esterification, yields the phthalate derivative (e.g.5a). Elaboration of the oxazoline-ring furnishes the related aldehydes which spontaneously cyclise to form the 3-hydroxyphthalides (8/10). The title[5-13C] anthracyclinone (20) is produced from 3-cyanophthalide (11) in good yield and with excellent isotopic efficiency. |
