  1，热水促进的烯丙醇的正重排：在合成多烯天然产物Navenone B中的应用

  摘要：

  首次报道，作为弱酸性催化剂的热水有效地促进了烯丙醇的1，n重排（n = 3、5、7、9 ）。在某些情况下，重排反应会连接孤立的C双键或C键，从而生成共轭多烯或烯结构的基序。我们使用了烯丙醇在热水中的1,3-重排反应作为通过反复使用格利雅（Grignard）反应构建多烯天然产物navenone B的有吸引力的新策略的一部分，将所得烯丙基的1,3-重排酒精和随后氧化的重排产物。

  Derivation and validation of the seasonal thermal structure of Lake Malawi using multi-satellite AVHRR observations

  摘要：

  Lake Malawi is the second largest lake in Africa by volume and an important regional source of food. Seasonal fluctuations in the primary production of the lake are principally controlled by the lake's thermal structure, which modulates the mixing of nutrient-rich deep water with that of the phytoplankton-rich near-surface layer. Satellites potentially offer an efficient, low cost method of providing information on the lakes thermal structure over the longer term via remote sensing observations of lake surface temperature. Here we investigate the accuracy of remotely sensed lake surface temperatures derived using data from the NOAA-11 AVHRR over a two-year period (1992-1993). Optimised triple window atmospheric correction algorithms are shown to provide an accuracy of around 0.5 degreesC when compared to in situ water temperatures. The effect of the 1994 switch in operational night-time satellite from NOAA-11 to NOAA-14 is assessed using modelling of the transfer of radiation through the Malawian atmosphere, combined with detail on the differences in the satellite spectral response functions. These simulations indicate that lake surface temperatures derived from NOAA-14 are warmer than those that would be derived from NOAA-11 under the same conditions. The magnitude of the temperature difference is estimated at 0.27 degrees+/-0.07 degreesC, depending on the viewing zenith angle. Finally, we illustrate the ability of the remotely derived surface temperature maps to provide information relevant to the lakes 3-D thermal structure. Evaluations of the annual mixing regime of the lake can be based on this information, this mixing being directly relevant to the seasonal variations in lake primary production.

  A novel calcium catalyst was found to efficiently functionalize electron‐rich arenes with secondary and tertiary benzylic, propargylic, and allylic alcohols under very mild reaction conditions. The new catalyst system significantly enlarges the scope of the reaction, which was previously limited except for the few examples with secondary benzylic alcohols.
