MODERN FRIEDEL-CRAFTS CHEMISTRY XVI. REACTION OF THIOPHENE WITH BIFUNCTIONAL MOLECULES UNDER DIFFERENT FRIEDEL-CRAFTS CATALYSTS: ATTEMPTED SYNTHESIS OF CYCLOPENTA[b] THIOPHENES AND DIHYDROBENZO[b] THIOPHENES

Alkyl, Unsaturated, (Hetero)aryl, and N-Protected α-Amino Ketones by Acylation of Organometallic Reagents

Stable and easily accessible N-acylbenzotriazoles, derived from a variety of aliphatic, unsaturated, (hetero)aromatic, and N-protected alpha-amino carboxylic acids, were reacted with Grignard and heteroaryllithium reagents to afford corresponding ketones in good to excellent yields.

Duloxetine (Cymbalta™), a dual inhibitor of serotonin and norepinephrine reuptake

A series of naphthalenyloxy-arylpropylamines have been prepared and are demonstrated to be inhibitors of both serotonin and norepinephrine reuptake. One member of this series, duloxetine (Cymbalta) has proven to be effective in clinical trials for the treatment of depression.
