Double nucleophilic addition of Thiols and allylstannane to alpha,beta-unsaturated aldimines promoted by titanium tetrachloride
In the presence of TiCl4, a mixture of thiol and tetraallyltin underwent 1,4- and 1,2-addition, respectively, with alpha, beta-unsaturated imines to give 6-sulfenyl-4-amino-1-alkenes in good yields.
