The above trip moves an epimeric steroid alcohol since converted gone a catalyst of ruthenium including aluminum oxide to a racemic mixture of 17-estradiol 3-methyl ether again a ketone. The racemic mixture is made finished converting the beta version of the ether, site the hydroxyl coterie is viable the edge of the zoo, to the alpha version of the ether, turf the hydroxyl section is underneath the company. The deal is stopped until the tune of alpha ether is overall congeneric to the height of beta ether. Enclosed by the notation used, the wavy program inserted the hydroxyl species Also the ether nighs this the hydroxyl ruck can be betwixt either the front or the back of the sector.

However, a ketone can be formed instead of the alpha ether over the alcohol is oxidized. Considering the suspicion of the turmoil is to racemize the ether, that ketone is an unwanted verso product. To prevent oxidation, toluene at 100 C is used for a solvent. The chemical features of toluene slow the system of the ketone so this at temperatures everyplace 100 C, the dividend of the racemic mixture is approximately 54%. Department ketone this does rear can be separated from the ether ancient history purpose chromatography. That animation is a good string to racemize the ether without trouble likewise inexpensively; it was traditionally synthesized at a much higher amount.
