revealing interesting synthetic challenges and constraints. Many of these limitations were overcome through the application of alternative reaction pathways in the construction of troublesome products. Treatment of the resultant Pmc-amidines with trifluoroacetic acid and trimethylsilyl trifluoromethanesulfonate cleanly afforded the deprotected substituted amidines. amidine - thioamide - Mukaiyama reagent
