The convenient and straightforward preparation of dideoxy-1,4- and 1,5-iminopentitol derivatives from protected sugar hemiacetals by way of N-tert-butanesulfinyl glycosylamines and open-chain aminoalditols is reported. The synthetic procedure is a method of choice for the making of these important scaffolds of biological interest.

The subject-matter of the present invention relates to the synthesis of new dendrimeric molecules based on polyhydroxylated pyrrolidines obtained by means of Click Chemistry reactions. The proposed molecules inhibit the enzymes N-acetylgalactosamine-6-sulfatase (GALNS), iduronate-2-sulfatase (IDS), a-mannosidase and β-glucosidase, deficient in lysosomal storage diseases. The presentation of multivalent iminosugars on a scaffold is a prerequisite for the inhibitory activity as the corresponding monomers are not active. The inhibitory activity reported is the basis for the development of the first-ASSC pharmacological chaperones proposed for the treatment of the above mentioned pathologies. Formula (I)

A highly diastereoselective synthesis of enantio-enriched all trans-3,4-dibenzyloxyl-5-benzyloxymethyl-2-pyrrolidinone 13a was developed based on SmI2-mediated benzyloxymethylation of O,O′-dibenzyltartarimide. The versatility of 13a and its antipode as the key building blocks for the asymmetric synthesis of pyrrolidine azasugars and homoazasugars has been demonstrated by elaborating them into naturally occurring DAB 1 (1), LAB 1 (2), N-hydroxyethyl-DAB 1 (4), 6-deoxy-DMDP 7, and 5-epi-radicamine B 36 as well as the reductive ring-opening product 35.
