  Stereoselective construction of quaternary centers at ambient temperature by the highly stereocontrolled migration of groups containing sp-, sp2-, and sp3-hybridized carbon atoms

  摘要：

  A very highly diastereoselective semipinacol rearrangement of 2,3-epoxy alcohols mediated by tin(IV) chloride at ambient temperatures is shown to be applicable to a wide variety of migrating groups including methyl, tert-butyl, cyclopropyl, vinyl, alkynyl, phenyl, and 2-furyl. A synthetically valuable feature is that a mixture of syn- and anti-epoxy alcohols affords only a single diastereoisomerically pure beta-hydroxy ketone. Additional advantages of the reaction include the presence in the product of two adjacent stereocenters and the efficient creation of a new quaternary center, valuable features in the synthesis of a variety of natural products.

  Efficient routes to cyclic 2,3-epoxyalcohols from cycloalkenyl ketones, via cycloalkenyl alcohols

  摘要：

  The minimising of torsional strain and non-bonding interactions is proposed as the explanation of high diastereoselectivity observed in the epoxidation of cycloalkenyl alcohols. reported for twenty three examples. The resulting 2,3-epoxyalcohols are key intermediates in the synthesis of tricyclic 1, 2-diols and beta-hydroxy ketones

  derived from ketones and chloromethyl phenyl sulfoxide or 1-chloroalkyl phenyl sulfoxides with lithium perchlorate in the presence of tributylphosphine oxide in toluene at 110 °C for about 1–3 h gave α,β-unsaturated aldehydes or α,β-unsaturated ketones in high yields. In contrast to these results, the α,β-epoxy sulfoxides derived from aldehydes did not give the desired α,β-unsaturated ketones. In this

  在三丁基氧化膦的存在下，在甲苯中，在 110 °C 的条件下，用高氯酸锂处理衍生自酮和氯甲基苯亚砜或 1-氯烷基苯亚砜的 α,β-环氧亚砜约 1-3 小时，得到 α,β-不饱和醛或高产率的 α,β-不饱和酮。与这些结果相反，衍生自醛的 α,β-环氧亚砜没有得到所需的 α,β-不饱和酮。在这种情况下，用苯硫醇和间氯过苯甲酸依次处理 α,β-环氧亚砜，得到 α-苯基亚磺酰化酮，将其在 110°C 的甲苯中加热，以良好的总产率得到所需的烯酮。通过该方法获得的α,β-不饱和醛的氧化以高产率得到α,β-不饱和羧酸。

  The combined use of a catalytic amount of InX3 (X = OTf and NTf2) and 1-butanol was found to be effective in formal alkyne–aldehyde metathesis. With this catalytic system, aromatic alkynes reacted with aromatic aldehydes to give chalcones in moderate to good yields. Alkynals were efficiently converted into 5- to 7-membered cyclic compounds by intramolecular alkyne–aldehyde coupling.

  Gold-catalyzed intermolecular oxidations of internal alkynes have been achieved with high regioselectivities using 8-alkylquinoline N-oxides as oxidants and in the absence of acid additives. Synthetically versatile α,β-unsaturated carbonyls are obtained in good to excellent yields and with excellent E-selectivities. A range of functional groups such as THP, MOMO, N(3), OTBS, and N-Boc are tolerated
