  On the importance of the stereochemistry at C10 in governing the feasibility of the intramolecular Diels-Alder route to baccatin III constructs: Surprising results in the 10R-9-deoxy series

  摘要：

  Upon surveying many experimental conditions in the title series, no simple type II IMDA reaction (leading to 15) was observed. A variety of alternative reactions are described.
