  Synthesis of the 5-hydroxymethyl-6-aryl-8-oxabicyclo[3.2.1]oct-3-en-2-one natural products descurainin and cartorimine

  摘要：

  Reaction of pyranulose 6 with styrenes 12c or 13 and Et3N in CH2O2 at 25 degrees C afforded the [5+2] cycloadducts 14c and 15, which were hydrolyzed to give the natural products I and descurainin (2) in 24 and 27% overall yield, respectively. Heating pyranulose 6 with cinnamate ester 21 in the presence of 2,6-di-t-butylpyridine in CH3CN at 175 degrees C afforded the [5+2] cycloadduct, which was hydrolyzed to give cartorimine (3) in 13% yield.
