Thioesters undergo soft enolization and direct Mannich addition to sulfonylimines on treatment with magnesium bromide ethyl etherate and N,N-diisopropylethylamine. The reactions proceed readily with a range of sulfonylimines and, in the case of 2,4,6-triisopropylphenyl thiopropionate, give moderate to good syn diastereoselectivity. enolates - imines - Mannich addition reactions - magnesium - thioesters
