  The first total synthesis and absolute stereochemistry of plakortone G from the Jamaican sponge Plakortis sp.

  摘要：

  Total synthesis of plakortone G (1), a secondary metabolite of the Jamaican sponge Plakortis sp., was successfully achieved. The absolute configuration of this molecule was determined by comparison of the synthetic diastereomers with reported data to possess the (4R,8R)-configuration 14. (C) 2004 Elsevier Ltd.

• Anomalous enantioselectivity in the Sharpless catalytic asymmetric dihydroxylation reaction of 1,1-disubstituted allyl alcohol derivatives

  日期：1994.1

  The Sharpless asymmetric dihydroxylation (AD) reaction has been examined on a number of 1,1-disubstituted allyl alcohol derivatives. In the majority of substrates studied, the product diols had ee's in the 11–91% range and had absolute stereochemistry opposite to that predicted using the Sharpless steric model.

  已对许多1,1-二取代的烯丙醇衍生物进行了Sharpless不对称二羟基化（AD）反应。在研究的大多数底物中，产物二醇的ee在11–91％范围内，并且绝对立体化学与使用Sharpless空间模型预测的相反。
