Abstrakt:	An efficient synthesis of (13α)-estrone derivatives containing pyran, isoxazole, or pyrazole moieties on the A-ring was performed based on difluoroborate complexes using the chelate methodology. Difluoroborate complexes were synthesized from (13α)-2-acetyl-3-hydroxyestra-1(10),2,4-trien-17-one. [ABSTRACT FROM AUTHOR]
