  1,2- and 1,3-diols examined was derivatized exclusively to a single diastereomeric acetal by the use of a new axially chiral reagent, 2′-methoxy-1,1′-binaphthalene-8-carbaldehyde (MBC). The absolute configuration of the original 1,2- and 1,3-diols was determined by the NOE correlation between the proton signals of the reagent moiety and those of the diol moiety in the acetals.

  通过使用新的轴向手性试剂2'-甲氧基-1,1'-联萘-8-甲醛（MBC），将所检查的每个手性1,2-和1,3-二醇专门衍生为一个非对映体缩醛）。通过缩醛中试剂部分的质子信号和二醇部分的质子信号之间的NOE相关性，确定了原始1,2-和1,3-二醇的绝对构型。
• Rapid Cyclic Acetal and Cyclic Ketal Synthesis Assisted by a Rotary Evaporator

  日期：——

  Herein, we present a rapid and efficient method for synthesizing cyclic acetals and ketals utilizing a rotary evaporator. Unlike the conventional Dean–Stark dehydration process, which typically demands extended reaction times and copious amounts of organic solvents, our approach affords the synthesis of cyclic acetals and ketals with varying ring sizes in 30 min while using minimal quantities of dimethyl

  在此，我们提出了一种利用旋转蒸发器快速有效地合成环状缩醛和缩酮的方法。与通常需要延长反应时间和大量有机溶剂的传统迪安-斯塔克脱水工艺不同，我们的方法可以在 30 分钟内合成具有不同环尺寸的环状缩醛和缩酮，同时使用最少量的二甲亚砜作为溶剂。该创新方案具有产量高、反应速度快、操作简单、底物适用性广等特点。
• Superacid-Catalyzed Reductive Friedel−Crafts Reaction of Arenes Using Arenecarbaldehyde Acetals
  作者：Shin-ichi Fukuzawa、Teruhisa Tsuchimoto、Tamejiro Hiyama

  日期：1997.1.1

  Reaction of 2-aryl-1,3-dioxane with arenes in the presence of a catalytic amount of trifluoromethanesulfonic acid gave the corresponding diarylmethanes in good to excellent yields. The acid-catalyzed Friedel-Crafts benzylation of arenes could altenatively be carried out using arenecarbaldehyde and 1,3-propanediol. The reaction was assumed to proceed through a redox process involving hydride shift from the cyclic acetal moiety to the benzylic carbon. The hydride shift was confirmed by the reaction with 5-ethyl-2-phenyl-4,4,6,6-tetradeuterio-1,3-dioxane, wherein more than 90% deuterium was incorporated into the benzylic carbon of the diphenylmethane. Diphenylmethyl ether Ph(2)CHOCH(2)CH(2)CH(2)OH also reacted with benzene to afford diphenylmethane under the same reaction conditions, suggesting that the ether should be the plausible intermediate that underwent the hydride shift.
