The preparation of piperidine- and pyrrolidinone-like polymer supported (R)-phenylglycinol derived scaffolds is described. Alkylation reactions were performed as a model transformation of these templates on the solid support which highlight some specific limitations in the use of (R)-phenylglycinol on the resin. Whereas the polymer supported piperidine was completely void of reactivity, alkylation of the pyrrolidinone counterpart proceeded with good yield, purity and control of mono- over bis-alkylation but with low diastereomeric excess.
