Construction of Diarylmethane Compounds. Synthesis of tolpropamine via Heck-Matsuda Reaction

Silva, Allan Ribeiro da ; Prediger, Patrícia ; Correia, Carlos Roque Duarte ;

Abstract:

Tolpopramine is a antihistamine and antipruritic drug used for skin diseases treatment such as allergy and itch. Previous syntheses relied on the Witting reaction to obtain 1-phenyl-1-(p-tolyl)ethane followed by hydroaminomethylation reaction using rhodium catalysis. This methodology does not provide conditions for an enantiosselective reaction. The compound 1 could be easily obtained from two Heck-Matsuda reactions from the N-protected allylamine 3.
