12b was unsuccessful with PCC even when carried out with AcONa as a buffer, since it provides an intractable mixture of compounds. Swern oxidation leads to the desired aldehyde (d,l)-4 which cannot be fully purified. That is the reason why the yield of (d,l)-5 was so low

13b that dimethyl ethylidene malonate reacts with isopropylidene triphenyl phosphorane (generated from isopropyl triphenylphosphonium iodide and n-Buli in THF, 20°C, 1 h) to provide the corresponding dimethyl 2-ethyl-cyclopropane-1,1-dicarboxylate (i) in 44 % yield when the reaction is carried out in THF (20°C, 24 h) (ii) in 14% yield when performed in the same solvent but at higher temperature (80°C, 24h) and (iii) in 70 % yield if performed in a THF-DMSO mixture (80°C, 6h)
