  • Acyclic stereoselection—13

    Li enolates of hindered aryl esters condense with aldehydes to give predominantly threo aldols. The method has been explored with esters 3 (DMP propionate), 4 (BHT propionate), and 5 (DBHA propionate). DMP propionate reacts with benzaldehyde and α-unbranched aliphatic aldehydes to give threo:erythro ratios of about 6.5:1. However, with α-branched aliphatic aldehydes, ester 3 gives only threo-aldols.
    受阻芳基酯的预先形成的锂烯酸酯与醛缩合,主要生成苏糖醛。已经使用酯3(DMP丙酸酯),酯4(BHT丙酸酯)和酯5(DBHA丙酸酯)探索了该方法。DMP丙酸酯与苯甲醛和α-非支链脂族醛反应,使苏-赤比为约6.5:1。然而,对于α-支链的脂族醛,酯3仅产生苏式醛醇。BHT丙酸酯和DBHA丙酸酯仅产生苏糖-研究了所有醛的醛醇。通过在含水甲醇中用KOH进行简单水解,可以将DMP羟醛转化为β-羟基酸。如果不进行逆醛醇缩合,则不能水解BHT醛。但是,这些醇醛可以还原为非对映体纯的1,3-二醇。可以通过涉及在硝酸乙腈水溶液中用硝酸铈铵(CAN)氧化的方法将DBHA醛醇转化为β-羟基酸。在DMP丁酸酯(15),DBHA丁酸酯(16),DMP戊烯酸酯(17)和BHT戊烯酸酯(18)的缩合物中还可以看到苏族选择性。该方法已被用于立体选择性合成外消旋胭脂红(30)的立体选择性。
  • Attainment of syn-selectivity for boron-mediated asymmetric aldol reactions of carboxylic esters

    日期:1998.4
    reagent for syn-selective aldol reactions has been developed based on the recent finding that the stereochemistry of the boron-mediated aldol reaction of a carboxylic ester is controlled by the bulkiness of the alcohol moiety of the ester, by the proper choice of reagents, and by the enolization conditions. This readily available, inexpensive reagent has been utilized in studies directed towards the synthesis
    为顺式选择性羟醛缩合反应的新的手性试剂已经被开发了基于最近的发现,即羧酸酯的硼介导的醛醇缩合反应的立体化学通过该酯的醇部分的膨松度的控制,通过适当选择试剂,并受烯醇化条件的影响。这种易于获得的廉价试剂已被用于大环内酯单萜内酯的合成研究中。

    [reaction: see text]Comprehensive analysis of the enolization of alpha-silyloxyketones by Chx2BCl/R3N has allowed us to design stereoselective Chx2BCl-mediated aldol processes that afford syn or anti aldol products and to disclose a hypothesis that accounts for the subtle effects that determine their enolization.
