  Thiazole-Based Synthesis of Formyl C-Glycosides

  摘要：

  A method for the installation of the formyl group at the anomeric position of pyranoses and furanoses starting from the corresponding lactones has been developed. The strategy involves the addition of 2-lithiothiazole to the sugar lactone, followed by the silane reduction of the acetylated resultant ketol and the unmasking of the formyl group from the thiazole ring. All steps have been studied in some details to improve chemical efficiency and stereochemical control. Hence, reversed alpha:beta ratios of ketols were found in kinetic and thermodynamic mixtures, the former being consistent with a steric effect control of the substituents and the latter by the electronic effect of the ring oxygen. Seven sugar aldehydes with different D-pyranosidic (2,3,4,6-tetra-O-benzyl-gluco, -galacto, and -manno, 2-azido-3,4,6-tri-O-benzyl-2-deoxy-galacto) and D-furanosidic moieties (5-O-benzyl-2,3-isopropylidene-ribo; 2,3,5-tri-O-benzyl-ribo; 2,3:5,6-di-O-isopropylidene-manno) were prepared in 52-65% isolated overall yield from the corresponding lactone.

  Deoxygenation of thiazolylketose acetates using SmI2–(CH2OH)2 or TMSOTf–Et3SiH affords thiazolyl C-glycosides with opposite α/β ratios. Examination of the thiazolyl α- and β-C-ribofuranoside pair by NOE experiments reveals that the earlier configuration assigned to one of these isomers has to be revised. Having prepared authentic anomeric α- and β-ribofuranose aldehydes from the corresponding thiazolyl

  使用SmI 2-（CH 2 OH）2或TMSOTf-Et 3 SiH对乙酸噻唑基酮糖乙酸进行脱氧，得到具有相反α/β比的噻唑基C-糖苷。通过NOE实验对噻唑基α-和β- C-核呋喃糖苷对的研究表明，必须修改分配给这些异构体之一的早期构型。已经制备正品异头α-和β-D-呋喃核糖醛从相应的噻唑基C ^由噻唑环的裂解-glycosides，各醛转化到（1→6） - c ^通过Wittig烯化-disaccharides与半乳糖6-正膦。

  With anticipation of the improvement in biological aspects in our SGLT2 program, novel pyridazinyl and thiazolyl analogs were designed and efficiently synthesized. The installation of the pyridazine ring at the anomeric carbon of D-glucopyranose was carried out in a stereoselective fashion. On the other hand, a series of thiazolyl analogs was also synthesized through a coupling reaction between perbenzyl gluconolactone 9 and 2-lithiothiazole. Biological activities of the compounds thus prepared were evaluated by the in vitro SGLT2 inhibition assay. Considering assay results, the novel benzylpyridazinyl and benzyl-thiazolyl analogs, disclosed in this article, could be a quick reference to prospective SGLT2 inhibitors useful for pharmacotherapy.

  The formylation at the anomeric carbon of the model sugars 2,3,4,6-tetra-O-benzyl-D-glucopyranose and 2,3:5,6-di-O-isopropylidene-D-mannofuranose is carried out by addition of 2-lithiothiazole to the corresponding lactones followed by reductive dehydroxylation and thiazole to formyl deblocking.
