  Total Synthesis of (−)-Jiadifenin

  摘要：

  As easy as ABCD: (-)-Jiadifenin was synthesized in eighteen reaction steps from 1-[(E)-(4'-bromo-2'-butenyl)oxy]-4-methoxybenzene. Key features of this synthesis include: 1) Ireland-Claisen rearrangement to produce the two contiguous quaternary centers at C5 and C6 simultaneously, 2) intramolecular Pauson-Khand reaction (IMPKR) to concurrently construct the A and B rings, and 3) [2+2] photo-cycloaddition to generate the all-carbon quaternary center at C9.

• On the selectivity of oxynitrilases towards α-oxygenated aldehydes

  Different α-alkoxy and α,β-di-alkoxy substituted aldehydes have been submitted to the catalytic action of the oxynitrilases from almond (PaHNL) or from Hevea brasiliensis (HbHNL), in order to explore the possibility of using these enzymes for the preparation of complex cyanohydrins. The selectivity of both enzymes towards these compounds was found to be largely dependent on the substitutents, being

  The suprafacial hydroxylation of olefins by osmium tetraoxide, though a much used synthetic method, would become even more important if three conditions could be met: (1) modification to achieve high and predictable enantioselectivity and acyclic diastereoselectivity, (2) clarification of reaction mechanism, and (3) facilitated recovery and recycling of osmium. This paper reports progress on all three

  四氧化锇表面羟基化烯烃虽然是一种常用的合成方法，但如果满足三个条件，则将变得更加重要：（1）改性以实现高且可预测的对映选择性和非环非对映选择性，（2）阐明反应机理， (3)促进锇的回收和再循环。本文报告了所有三个方面的进展。
• Selective Monoalkylation of Acyclic Diols by Means of Dibutyltin Oxide and Fluoride Salts.
  作者：Nobuo NAGASHIMA、Masaji OHNO

  DOI：10.1248/cpb.39.1972

  日期：——

  Fluoride anion was found to promote monoalkylation reaction of diols by the stannylene acetal method, and selective monoalkylation of various acyclic diols was accomplished in good yields under mild conditions by employing this new method. Functional groups such as carboxylic acid ester, carboxamide, carbamate, nitrile, alkyl chloride, and ether were not affected under the reaction conditions.
