2-Substituted 5-alkylidene-6-(dimethylamino)methyl-1,3-cyclohexadienes (E)-4 and (Z)-4 were prepared by the reaction of α,4-disubstituted dimethyl[(trimethylsilyl)methyl]benzylammonium iodides 2 with cesium fluoride. Their E-isomers were stable at room temperature and could be used in the Diels-Alder reaction. Some related reactions are also described.

The present invention relates to compounds of general formula (I) in particular for use in the treatment of senescence-related diseases, such as idiopathic pulmonary fibrosis, sarcopenia, diabetes, obesity, osteoarthritis, chronic inflammations, glaucoma, cataracts, radiation-induced oral mucosis, renal transplantation, prostatic hyperplasia.
Aerobic Oxidation of 4-Alkyl-<i>N</i>,<i>N</i>-dimethylbenzylamines Catalyzed by <i>N</i>-Hydroxyphthalimide: Protonation-Driven Control over Regioselectivity
acetonitrile following addition of 0.1 M HClO4. This acid-induced change in regioselectivity has been successfully applied for selective functionalization of the less activated benzylic C–H bonds para to the CH2N(CH3)2 group in the aerobicoxidation of 4-alkyl-N,N-dimethylbenzylamines catalyzed by N-hydroxyphthalimide in acetic acid.
