Abstract
The invention concerns a method of preparation of aminomethyltriorganotin compounds, preferably .alpha.-mono or disubstituted, the new tin compounds obtained thereby and an application of said tin compounds to the synthesis of aminomethylorganometallic compounds and to the regiospecific preparation of .beta.-aminoalcohols. The intermediate tin and metallic compounds are new. The method for preparing the tin compounds comprises reacting an iminium salt with a corresponding stannylanion, preferably a triorganostannylanion. This method provides best yields and provides regiospecific .beta.-aminoalcohols useful by having in most cases a large spectrum of pharmacological activities.
