  摘要：

  在1,2-二甲氧基乙烷、1,2-二乙氧基乙烷或二甘醇中，对甲苯磺酰基苯甲酸甲酯的热分解和光化学分解会产生苯甲醛二甲基缩醛、苯甲酸甲酯腙（II）、meso-1,2-二苯基-1,2-二甲氧基乙烷和甲基α-(对甲苯磺酰基)苄醚。在存在己烯二酸二乙酯的情况下，热分解产生了产率为62%的二乙酯3-甲氧基-3-苯基-反-1,2-环丙烷二甲酸酯（XIV）；在1-癸烯中形成了产率为4%的1-甲氧基-2-正辛基-1-苯基环丙烷（V）的两种异构体，热分解和光化学分解钾4-戊烯基苯甲酸甲酯（对甲苯磺酰基）腙（XVIII）分别产生了1-苯基-2-氧代双环[4.1.0]庚烷（XXI），产率分别为14%和21%。这些产物为烷氧基重氮烷和烷氧基碳负离子在酯（对甲苯磺酰基）腙盐分解中的发生提供了额外证据，并暗示了烷氧基碳负离子可能是可能的中间体。

  日期：——

  Dipent-4-enyl acetals, which are congeniently prepared by treating ketones or aldehydes with pen-4-enyl alcohol under standard conditions, readily acetalize diols in acetonitrtile solvent, and although neutral promoters such as N-halogenosuccinimides and iodonium dicollidine peerchlorate are effective, the rates and yields are greatly enhanced by the addition of catalytic amounts of an acid.

  4-戊烯基缩醛，通过在标准条件下用4-戊烯醇处理酮或醛而天然制备，在乙腈溶剂中容易缩醛化二醇，尽管中性促进剂如N-卤代琥珀酰亚胺和碘鎓二可力丁高氯酸盐有效，但加入少量酸作为催化剂可以显著提高反应速率和产率。

• A Solvation-Assisted Model for Estimating Anomeric Reactivity. Predicted versus Observed Trends in Hydrolysis of <i>n</i>-Pentenyl Glycosides¹

  An attempt has been made to predict qualitative trends in reactivity at the anomeric center, using N-bromosuccinimide-induced hydrolysis of n-pentenyl glycosides (NPGs) as the experimental model. Calculated relative activation energies based on internal energy differences between a reactant and the associated intermediate are not always in agreement with experimental observations. However, solvation energies obtained by the generalized Born surface area model in MacroModel developed by Still et al. give modified activation energies that are in excellent agreement with the experimentally observed trends. It is shown that the solvation model does not disturb the normally observed reactivity trends that can be rationalized on the basis of internal energies alone. The value of the methodology has been demonstrated for several substrates by first-calculating their relative activation energies, then testing them experimentally, and finding excellent agreement with predictions.
