1. Four-carbon Wittig homologation of the piperonal–cyclobutanone aldol-fragmentation product, a hypothetical route to alkaloids such as retrofractamide A, was thus not viable. Instead, three-carbon homologation of the readily available piperonal–cyclopentanone product, using alkyne chemistry recently disclosed by Lu and Trost, afforded these alkaloids in excellent overall yield.

2. An FE-analysis on the virtual full vehicle puts in evidence a good structural behaviour, considering EU crash standards of homologation and global static and dynamic performances.

3. The installation of the retarder (and transmission) shall be done with an inclination angle as for installation in the vehicle according to the homologation drawing ± 1° or at 0° ± 1°.
