The Ritter reactions of 3-alkyl-3-hydroxyazetidine or -piperidine derivatives give low yields of the desired products, whereas the 3-alkyl-3-hydroxy-pyrrolidine and 4-alkyl-4-hydroxy-piperidine derivatives react smoothly to give the corresponding acetamides. An alternative route to 3-acylamino-3-alkylpiperidines, which were designed as conformationally-restricted reduced amide dipeptide isosteres, was devised from nipecotic acid vai a Hofmann rearrangement.
