    Asymmetric Dihydroxylations of 1-Substituted (E)- and (Z)-3-Methylpent-2-en-4-ynes: Full Compliance with the Sharpless Mnemonic Re-established and Embellished
    摘要:
    Asymmetric dihydroxylations ("ADs") of the pentenynyl chlorides (E)- and (Z)-1 or the pentenyne-based ester (Z)-3 in the presence of (DHQ)(2)-containing ligands delivered diol stereoisomers (2R,3S)-2, (2R,3R)-2, and (3S,4R)-4, respectively. The ADs of pentenynyl ethers (E)-10 and (Z)-12, respectively, have the same stereochemical preference under analogous conditions; these reattributions correct previous reports of the contrary. The Sharpless mnemonic rationalizes all these results implying that each substrate prefers a Sharpless/Norrby instead of a Chapleur orientation in the transition state.

  • Anodic Oxidation: An Attractive Alternative to CAN-Mediated Cleavage of<i>para</i>-Methoxyphenyl Ethers

    para-Methoxyphenyl (PMP) ether is a very convenient protecting group for the alcohol function; however, its cleavage requires strong oxidative conditions. In this field, the use of powerful ceric ammonium nitrate has been widely described, despite the fact that its strong nature results in the formation of degradation products in acid- or oxidation-sensitive substrates. In this paper, a new anodic
    对甲氧基苯基 (PMP) 醚是一种非常方便的醇功能保护基团;然而,它的裂解需要强氧化条件。在该领域中,强力硝酸铈铵的使用已被广泛描述,尽管其强性质导致在酸或氧化敏感底物中形成降解产物。本文报道了一种在弱碱性介质中裂解对甲氧基苯基醚的新阳极氧化方法。该方法是避免使用硝酸铈铵的有吸引力的替代方法。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2009)

    Coupling of the different protected (hydroxymethyl)enynes 11a-e and 12a-c with the iodoarene 7 in the presence of catalytic amounts of Pd(PPh3)4 afforded the arylenynes 5a-e and 6a-c which were transformed into the monoprotected chiral trihydroxy compounds 13a-d and 14a,b by Sharpless bishydroxylation with >95% ee for 13a-d, 91% ee for 14b and 64% ee for 14a. A 5-step transformation of 13a led to the desired chroman derivative 3a which was cleaved to give the aldehyde 2 a known precursor for the enantioselective synthesis of vitamin E.
