  ABSTRACT The reaction of D-glucal and its derivatives with the electrophilic N-F-fluorination reagents F-TEDA tetrafluoroborate and triflate was studied by means of 19F NMR spectroscopy. In all cases mixtures of 2-deoxy-2-fluoro-D-gluco- and -D-mannopyranose derivatives were formed, the ratio of which was dependent on the nature of the O-protecting groups. Concerning the products arising from the direct

  摘要利用19F NMR光谱研究了D-葡萄糖及其衍生物与亲电NF-氟化试剂F-TEDA四氟硼酸酯和三氟甲磺酸酯的反应。在所有情况下，均形成2-脱氧-2-氟-D-葡萄糖-和-D-甘露吡喃糖衍生物的混合物，其比例取决于O-保护基团的性质。关于直接通过双键添加试剂产生的产物，D-葡萄糖构型的化合物（13-20）通常显示出比其D-甘露聚糖对应物（21-28）更高的水解速率。仅当形成单个端基异构体（例如2,4-二硝基苯基糖苷29e / 37e和二糖氟化物35d / 43d）或过氧乙酸酯（例如29f / 37f）时，才能实现产品分离。

Treatment of iodoisothiocyanates 7, 11, 13–15 with ammonia gives the corresponding 2-amino-thiazolines 16, 17, 23–25, respectively. Under the same conditions, iodoisothiocyanate 8 affords the iodothiourea 18. 2-Amino-2-thiazolines 23–25 can be readily transformed into

  procedure for the synthesis of glycals from glycosyl bromides with very low zinc dust loading (1.5 equiv.) is described. The process is activated by β‐cyclodextrin and ultrasound. Based on 19 samples, this method has been demonstrated to be highly effective for a broad range of glycosyl bromides, including acid‐ or base‐sensitive and disaccharide glycosyl bromides. A yield of 85%–96% of glycals was obtained

• The Synthesis of Some Epoxyalkyl b-C-Glycosides as Potential Inhibitors of b-Glucan Hydrolases

  The treatment of tetra-O-benzyl-D-glucono-1,5-lactone with various alkenylmagnesium halides gave the intermediate lactols which, upon reduction (Et3SiH/BF3) and protecting group manipulation, yielded alkenyl tetra-O-acetyl-β-D-C-glucopyranosides in good yield. These β-D-C-glucosides were precursors of the epoxyalkyl β-D-C-glucopyranosides, themselves putative inhibitors of b-glucan hydrolases. Similar additions of Grignard reagents to per-benzylated cellobionolactone were not as successful in yielding epoxyalkyl β-C-cellobiosides. The addition of Grignard reagents to 1,2-anhydro-3,4,6-tri-O-benzyl-α-D- glucose offers a viable alternative route to the prop-2-enyl β-D-C-glucoside, but not to the but-3-enyl and pent-4-enyl counterparts. Likewise, the addition of Grignard reagents to a 1,2-anhydro cellobiose gave disappointing results. Preliminary results are reported for a novel approach to alkenyl β-D-C-glucosides by the alkylation of nitromethyl β-D-C-glucosides.
