Page/Page column 7; 8, (2016/05/02)
The patent discloses novel diol derivatives of general formula I, [Formula should be inserted here] A chiral pool process for the synthesis of the compound of formula I from D glucose. Further, it discloses a process for the synthesis of (2R, 3S)-3-hydroxypipecolic acid from D- glucose using chiral pool approach, wherein the D-glucose used is in enantiomerically pure form.

Stannyl radical-mediated cyclization of oxime ethers (6), (14), (22), and (29) derived from glucose and galactose afforded the cyclized aminosugar derivatives (7), (8), (15, 16 and 17), (23), (24), and (30, 31 and 32) which would serve as key intermediates for the synthesis of dysiherbaine and its isomers.

The D-manno-configured N-anisylated β-lactam 40, the β-lactam carboxylic acids 4 and 43, and the corresponding phosphonic-acid isosters 49 and 50 have been synthesized from D-glucose in 8-10 steps, respectively. None of these compounds exhibited a significant inhibitory activity in vitro against the sialidases of Vibrio cholerae, Salmonella typhimurium, Influenza A (N9), and Influenza B virus. Cycloaddition of the in situ generated imines derived from the D-erythroses 6, 16, and 17 with the ketene from mesyloxyacetyl chloride (20) gave the 2-mesyloxy-D-hexono-1,3-lactams 25, 27a/b, 28a/b/c, and 29 in 23, 69, 57, and 90% yield, respectively (Scheme 3). Transformation of 27a/b and 29 (> 85%) to the corresponding azides, followed by oxidative N-deprotection, gave 30a/b (45%) and 34 (80%). Subsequent alkylation of the ring N-atom in 31a with benzyl bromoacetate and dibenzyl (triflyloxymethyl)phosphonate 46 gave the carboxylate 41 (77%) and the phosphonate 47 (55%; Schemes 4 and 5). Hydrogenolysis of 41 gave the β- lactam amino acid 43, besides its hydrolysis product 44. Reductive N- acylation of the azido group in 41 (93%), followed by hydrogenolytic debenzylation, yielded the 2-trifluoroacetamido N-(carboxymethyl)-β-lactam 4 (56%). Similarly, 47 gave the 2-trifluoroacetamide 48 (89%), and hence, the 2-amino-N-(phosphonoylmethyl)-β-lactams 49 (40%) and 50, resulting from deacylation of 49 (14%). Aminolysis and carbamoylation of the protected β- lactams 31a and 35 led to the 2,3-diamino-2,3-dideoxy-D-mannonamides 51 and 53, respectively (Scheme 6).
