Enantioselective synthesis of (+)-estrone exploiting a hydrogen bond-promoted Diels-Alder reaction.

J. Org. Chem. 75 , 2718-2721, (2010)

Starting from Dane's diene and methylcyclopentenedione, (+)-estrone is synthesized along the Quinkert-Dane route in 24% total yield. The key step is an enantioselective Diels-Alder reaction promoted b...
