Boron annulation, hydroboration-carbonylation, of substituted 1,5,9-decatrienes was utilized to prepare the cadinane sesquiterpene system. Stereochemical aspects of the triene hydroboration process and the carbonylation reaction have been analyzed through glc separation of boronate esters. Structural assignments for these esters and their oxidation (H2O2/NaOH) products were made through high field
硼取代,硼氢化羰基化,取代的1,5,9-癸二烯被用来制备卡丹烷倍半萜烯系统。通过硼酸酯的glc分离分析了三烯硼氢化过程和羰基化反应的立体化学方面。这些酯及其氧化产物(H 2 O 2 / NaOH)的结构分配是通过高场1 H-NMR以及其他物理和光谱方面的考虑进行的。
