High-Throughput Experimentation (HTE) workflows are efficient means of surveying a broad array of chiral catalysts in the development of catalytic asymmetric reactions. However, use of traditional HPLC-UV/vis methodology to determine enantiomeric exc

Using a commercially available, inexpensive, and abundant copper catalyst system, an efficient α–functionalization of nitroalkanes with propargyl bromides is now established. This mild and robust method is highly functional group tolerant and prov

We report an asymmetric Ullmann-type homocoupling of ortho-(iodo)arylphosphine oxides and ortho-(iodo)arylphosphonates that results in highly enantioenriched axially chiral bisphosphine oxides and bisphosphonates in good yields and excellent enantios

Phosphonate-directed ortho C–H borylation of aromatic phosphonates is reported. Using simple starting materials and commercially accessible catalysts, this method provides steady access to ortho-phosphonate aryl boronic esters bearing pendant funct

Over the past forty years, intramolecular hydroacylation has favored five-membered rings, in preference to four membered rings. Herein, we report a catalyst derived from earth abundant cobalt salts that enables preparation of cyclobutanones, with exc
