A process for the preparation of 11-methylene steroids from di-keto steroids involves selective olefination of the ketone at position 11 of the di-keto steroids. The resulting 11-methylene steroid products can be used as intermediates in the preparation of the synthetic steroids, Etonogestrel and Desogestrel, as well as other pharmaceutically active agents.

The present invention refers to a process for transition-metal-assisted .sup.18F-deoxyfluorination of phenols. The transformation benefits from readily available phenols as starting materials, tolerance of moisture and ambient atmosphere, large substrate scope, and translatability to generate doses appropriate for positron emission tomography (PET) imaging.

The invention provides novel neuroactive steroids and pharmaceutical compositions thereof, as well as methods of their preparation and use, in therapy of various diseases and conditions, for example, various neurological or brain diseases.

The present disclosure relates to stereodefined polycyclic (e.g., tetracyclic) compounds that contain quaternary centers at one or multiple ring fusions, synthetic methods for preparing such compounds, and methods of using such compounds to treat a disease, such as a brain tumor and, particularly, a glioma.

Provided herein are 3,3-disubstituted 19-nor-steroidal compounds according to Formula (I):

##STR00001##

and pharmaceutical compositions thereof. Such compounds are contemplated useful for the prevention and treatment of a variety of CNS-related conditions, for example, treatment of sleep disorders, mood disorders, schizophrenia spectrum disorders, disorders of memory and/or cognition, movement disorders, personality disorders, autism spectrum disorders, pain, traumatic brain injury, vascular diseases, substance abuse disorders and/or withdrawal syndromes, tinnitus, status epilepticus.

Methods of preparing fluorinated compounds by carboxylative fluorination using fluoride are contained herein. Fluorinated compounds are provided. Methods of using fluorinated compounds are contained herein.

In some aspects, the present disclosure provides methods of aminating an aromatic compound comprising reacting an aminating agent with an aromatic compound in the presence of a rhodium catalyst. In some embodiments, the methods may comprise aminating an aromatic compound which contains multiple different functional groups. The methods described herein may also be used to create bicyclic system comprising reacting an intramolecular aminating agent with an aromatic ring to obtain a second ring containing a nitrogen atom. In another aspect, the methods described herein may also be used to create a cyclic aliphatic cyclic/poly cyclic amine system comprising a reacting an intramolecular aminating agent by insertion into a C(sp3)-H bond.
