3,15-substituted estrone compounds which act as inhibitors of 17β-hydroxysteroid dehydrogenase type I (17β-HSD1), salts thereof, pharmaceutical preparations containing such compounds, processes for preparing such compounds, and therapeutic uses of such compounds, particularly in the treatment or inhibition of steroid hormone dependent diseases or disorders, such as steroid hormone dependent diseases or disorders requiring the inhibition of 17β-hydroxysteroid dehydrogenase type I enzymes and/or requiring the lowering of the endogenous 17β-estradiol concentration, as well as the general use of selective 17β-hydroxysteroid dehydrogenase type 1 inhibitors which possess in addition no or only pure antagonistic binding affinities to the estrogen receptor for the treatment or inhibition of benign gynecological disorders, particularly endometriosis.

of our most recent study using the thio-Claisen rearrangement for the synthesis of anti-β-functionalized γ,δ-unsaturated amino acids. Investigations on scope, limitations, chemoselectivities and stereoselectivities regarding an FeBr3-catalyzed allylation strategy and a thio-enolate dianion formation strategy for asymmetric thio-Claisen rearrangement are documented. An explanation of the chirality crossover
