Synthesis of amphiphilic polyhydroxylated pyrrolidines as potential glycosidase inhibitors
摘要:
Several polyhydroxylated pyrrolidines with an aliphatic long chain on the ring nitrogen were prepared starting from D-mannitol. An amphiphilic bis-azasugar scaffold has been also prepared. These products behave as cationic surfactants and show a promising anti HIV-I activity. (C) 1998 Elsevier Science Ltd. All rights reserved.

D-mannitol and L-iditol bis-epoxides, easily obtained fromD-mannitol, are convenient substrates for the synthesis of polyhydroxylated piperidines and azepanes, via a nucleophilic opening of one epoxy function followed by a spontaneous intramolecular ring closure. Using this strategy 1-deoxynojirimycin and analogues were prepared.

A series of enantiomerically pure azasugars (2,5-dideoxy-2, 5-imino-D-mannitol, 1-deoxynojirimycin, 1-deoxymannojirimycin, and related compounds) was synthesized from D-mannitol via aminoheterocyclization of C2-symmetric bis-epoxides and subsequently followed by ring isomerization in few cases. These compounds have been evaluated as inhibitors of several glycosidases (alpha- and beta-D-glucosidases

This Letter describes an efficient synthesis of a range of 1'-homo-N-nucleoside mimetics with a series of 4-substituted 1,2,3-triazoles replacing the natural nucleobase. The synthesis of 6-O-monosulfated 1'-homo-N-nucleoside mimetic derivatives is also discussed. (C) 2011 Elsevier Ltd. All rights reserved.

The synthesis of 2,5-anhydro-D-glucitol is described via intramolecular cyclization of diepoxide using ammonium formate in MeOH by a microwave-assisted reaction. The overall yield was 32% from D-mannitol derivative involving seven steps. (C) 2012 Elsevier Ltd. All rights reserved.
