Synthetic Approach to 4a-Methyltetrahydrofluorene-Type Diterpenoids via an Aromatic Oxidation of Phenol Derivatives
摘要:
An intramolecular aromatic oxidation of a phenolic compound with a hypervalent iodine reagent afforded the coupling product, in which the coupling took place at the para-position of the methoxy goup of the starting material instead of the desired para-position of the isopropenyl group, unfortunately.

efficient construction of a series of chiral phenanthrenone derivatives bearing an all‐carbon quaternary center. The effectiveness of this method in the synthesis of terpenes and steroids was demonstrated by a highly efficient synthesis of a kaurene intermediate, the facile construction of the skeleton of the anabolic steroid boldenone, and the enantioselective totalsynthesis of the antimicrobial diterpene
