methylenated to the corresponding acyl enamines16 or 17 with in situ generated chloromethylmagnesium chloride. Naphthalene-catalysed lithiation of α-aminomethyl sulfone 19 in the presence of electrophiles [ButCHO, PhCHO, Et2CO, Pr2iCO, (CH2)5CO, PhCOMe] at −78 to 0°C leads, after hydrolysis with water, to the expected aminoalcohols 20. The application of this method to α-amidomethyl sulfones 7c,d using
Deprotonation of α-amido sulfones 7 with BunLi at -90°C followed by reaction with electrophiles leads, depending on the substitution on the amidic nitrogen to enamides 10 (secondary amides 7a,b) or functionalised α-amido sulfones 12 (tertiary amides 7c,d).
