Embodiment 1a
[0032] Embodiment 1a: under ice-water bath, compound 14 counts 4.88g (11.0mmol), 10%Pd / C 0.20g, Na 2 CO 3 0.24g and MeOH 100mL were vigorously stirred for atmospheric catalytic hydrogenation for 2.0h. Filtration, the filtrate was washed with 1.0M NaH 2 PO 4 / Na 2 HPO 4 The buffer solution was diluted with 100 mL, and concentrated under reduced pressure to recover methanol. The residue was extracted with ethyl acetate and dried over anhydrous sodium sulfate. After concentration, the crude product was separated by column chromatography to obtain 3.04 g of white solid 12 with a yield of 62.0%. m.p 104~106℃,[α] D20 =+82.88(c 1.0, CHCl 3 ).
[0036] Example 1b: Under similar conditions, 10% Ru / C 0.25g was used instead of Pd / C in Example 1a, and 2.89g of 12 was obtained after similar post-treatment, with a yield of 59.0%.
Embodiment 1c
[0037] Example 1c: Under similar conditions, 0.40 g of Raney / Ni(W–2) was used instead of Pd / C in Example 1a. After similar post-treatment, 2.40 g of 12 was obtained, with a yield of 49.0%.

Abstract
The present invention belongs to the field of pharmacy, and specifically relates to 3-deoxy-5-hydroxyl-1-amino carbon sugar compounds with the following general formula and uses thereof, wherein R is as described in the claims and description. The invention synthesizes protected 3-deoxy-5-hydroxycyclohexanone through a stereo and position selective reduction method, and the compound has a novel carbon sugar skeleton. The compound is reacted with small molecule amines by reductive amination method to obtain the target object protected by the corresponding protecting group, and finally the aminocarbon sugar target object with 3-deoxy-5-hydroxyl structural characteristics is obtained through deprotection group reaction. The target substance has good inhibitory activity on α-glucosidase, and has a significant inhibitory effect on the blood sugar rise after sucrose loading in normal ICR mice, suggesting that it can be used for further development of hypoglycemic drugs.
Description
technical field [0001] The invention belongs to the field of pharmacy, and relates to 3-deoxy-1-hydroxyl-5-amino carbon sugar compounds and applications thereof. Background technique [0002] The oxygen atom (-O-) in the carbon sugar molecular ring is replaced by the methine group (-CH 2 -) The replacement product, after the replacement, it still retains the basic skeleton or structural characteristics of the original sugar, has similar biological activity, but has a more stable chemical structure and more stable biological characteristics (McCasland G.E., et al., J . Org. Chem., 1966, 31, 1516). As carbon sugar mimetics (mimetics) have been widely researched and reported compounds, with hypoglycemic activity, etc.; can also be used as the backbone of sugar in nucleoside or nucleotide molecules, showing antibacterial, antitumor or antiviral activities (Lahiri R., et al., Chem. Soc. Rev., 2013, 42, 5102). [0003] Commercially available drugs acarbose (acarbose, 1) and vog...
