Studies Directed toward the Total Synthesis of Azasteroids. I. 3,4-Cyclopenteno-5,6-dihydropyridines and 6,6-Tetramethylene-5,6-dihydro-1,3-oxazines1-3
Various 1,4‐diols are easily accessible from alkenes through iron‐catalyzed aerobic hydration. The reaction system consists of a user‐friendly iron phthalocyanine complex, sodium borohydride, and molecular oxygen. Furthermore, the effect of additional ligands on the iron complex was examined for a model reaction. The second hydroxy group is installed by direct C(sp3)H oxygenation, which is based on
