Abstract
... The Journal of Organic ... Mechanistic insight is also provided from a time course of 19 F NMR. ... However, the application of Wiemer's protocol(14b) to 3 gave a minor, crystalline byproduct 4, which in turn provided the first X-ray crystal structure of the skeleton of (+)-sclareolide ...
