Hydroxylated Piperidines: Synthesis of 1,5-Alkylimino-1,5-Dideoxy Derivatives of Xylitol, d- and l-Arabinitol, and Ribitol

Direct routes are reported for the synthesis of N-propyl, N-butyl- and N-pentyl-1,5-dideoxy-1,5-iminoxylitol (7a,b,c), the analogous derivatives (8a,b,c, and 9a,b,c) of 1,5-dideoxy-1,5-imino-d- and -l-arabinitol, and of N-propyl-1,5-dideoxy-1,5-iminoribitol (10).
