Catalytic Enantioselective Arylboration of Alkenylarenes

A method for the catalytic enantioselective arylboration of alkenylarenes is disclosed. The reaction leads to the formation of 1,1-diarylalkanes that also incorporate an additional pinacol boronic ester which can be easily transformed to a variety of groups. The products are formed with excellent diastereoselectivities and enantioselectivities.

Rhodium-catalyzed enantioselective conjugate addition of arylboronic acids to dihydronitronaphthalenes

A highly enantioselective (up to 91% ee) rhodium-catalyzed asymmetric addition of arylboronic acids has been achieved leading to the challenging dihydro-3-nitronaphthalenes using one equivalent of phosphoramidite ligand to rhodium catalyst. A concise formal asymmetric synthesis of the dopamine D1 agonist, dihydrexidine was accomplished using the method. Copyright

Asymmetric synthesis of a dopamine D1 agonist, dihydrexidine from d-serine

A scalable asymmetric synthesis of trans-2-amino-6,7-dimethoxy-1- phenyltetralin 2 and its N-nosyl derivative 12 have been achieved from Garner aldehyde derived from easily available d-serine using a stereoselective PhMgBr addition, Wittig reaction and TF

Asymmetric synthesis of the dopamine D1 agonist, dihydrexidine

A concise asymmetric synthesis of first, high affinity domaine D1 full agonist, dihydrexidine has been accomplished via catalytic enantioselective aziridination and subsequent one-pot Friedel-Crafts cyclization of an in situ generated tethered aziridine w

METHOD OF ADMINISTRATION OF DOPAMINE RECEPTOR AGONISTS

Methods for treating a patient having pulmonary edema are described. The methods include administering to the lung endobronchial space of the airways of the patient an effective amount of a dopamine D1 receptor agonist. Dopamine D1 receptor agonists, including hexahydrobenzophenanthridine, hexahydrothienophenanthridine, phenylbenzodiazepine, chromenoisoquinoline, naphthoisoquinoline dopamine receptor agonists, and their pharmaceutically acceptable salts, formulated as aerosols and dry powders are also described.

The first asymmetric synthesis of a dopamine D1 agonist, dihydrexidine, employing asymmetric conjugate addition technology

The first asymmetric synthesis of benzophenanthridine dopamine D1 full agonist, dihydrexidine, was accomplished employing three key processes, external chiral ligand-controlled conjugate addition of phenyllithium, Curtius conversion of a carboxylic group
