    摘要:
    在含水甲醇,乙醇,三氟乙醇以及乙醇和三氟乙醇的二元混合物中监测2-脱氧-α-和β-D-吡喃葡萄糖基4'-溴代异喹啉鎓四氟硼酸盐的溶剂化物(1和2)。观察到的速率常数与通过解离(D(N)A(N))过渡态进行的1和2的溶剂解一致。与α-异头物相比,β-化合物的溶剂分解使过渡态电荷离域到环氧原子上更大。溶剂分解产物比率的分析表明,在所研究的溶剂混合物中,2-脱氧葡萄糖基氧杂碳鎓离子未达到溶剂平衡。在化合物1的溶剂分解中,溶剂三氟乙醇有助于离去基团的扩散分离,因此,

  • Synthetic utility of 1,1,2,2-tetraaryldisilanes: radical reduction of alkyl phenyl chalcogenides
    作者:Osamu Yamazaki、Hideo Togo、Masataka Yokoyama
    DOI:10.1039/a905937g
    日期:——
    Reactivity of tetraaryldisilanes as radical reducing agents of alkyl phenyl chalcogenides initiated by Et3B or AIBN was studied. Here, the reactivity of alkyl sulfide was poor; however, various alkyl phenyl selenides and tellurides were reduced to the corresponding hydrocarbons in good yields with 1,1,2,2-tetraphenyldisilane.

    日期:1994.9
    Bis(trifluoroacetoxy)iodobenzene can be used for studying the stereoselectivity of O-glycosylation from thioglycosides and the use of reagent-stabilized sulfonium ions to prohibit the formation of oxonium ions is also discussed.

    作者:Robin Jeanneret、Carlo Walz、Maarten van Meerbeek、Sarah Coppock、M. Carmen Galan
    DOI:10.1021/acs.orglett.2c02530
    日期:2022.9.2
    A new practical, catalytic, and highly stereoselective method for directly accessing 1,1-α,α′-linked 2-deoxy trehalose analogues via AuCl3-catalyzed dehydrative glycosylation using hemiacetal glycosyl donors and acceptors is described. The method relies on the chemoselective Brønsted acid-type activation of tribenzylated 2-deoxy hemiacetals in the presence of other less reactive hemiacetals.

  • Erosion of Stereochemical Control with Increasing Nucleophilicity: <i>O</i>-Glycosylation at the Diffusion Limit
    作者:Matthew G. Beaver、K. A. Woerpel
    DOI:10.1021/jo902222a
    日期:2010.2.19
    Nucleophilic substitution reactions of 2-deoxyglycosyl donors indicated that the reactivity of the oxygen nucleophile has a significant impact on stereoselectivity. Employing ethanol as the nucleophile resulted in a 1:1 (alpha:beta) ratio of diastereomers under S(N)1-like reaction conditions. Stercoselective formation of the 2-deoxy-alpha-O-glycoside was only observed when weaker nucleophiles, such as trifluoroethanol, were employed. The lack of stercoselectivity observed in reactions of common oxygen nucleophiles can be attributed to reaction rates of the stereochemistry-determining step that approach the diffusion limit. In this scenario, both faces of the prochiral oxocarbenium ion are subject to nucleophilic addition to afford a statistical mixture of diastercomeric products. Control experiments confirmed that all nucleophilic substitution reactions were performed under kinetic control.
