Reaction of 2-(cycloprop-1-en-1-yl)ethanol derivatives with bromine, acid or silver ion generally leads to ring expansion, either to 5,6-dihydro-2H-pyrans or to 3-methylenetetrahydrofurans.
Described herein are compounds which either act as pure antiprogestins or as antiprogestins with partial agonistic activity and methods of treating cancer using such compounds.
