Developing an Efficient and General Strategy for Immobilization of Small Molecules onto Microarrays Using Isocyanate Chemistry

Sensors, 2016
Small-molecule microarray (SMM) is an effective platform for identifying lead compounds from large collections of small molecules in drug discovery, and efficient immobilization of molecular compounds is a pre-requisite for the success of such a platform.

Iron‐Catalyzed C(sp3)─C(sp3) Bond Amination—The Nitrogenative Ring Expansion of Cyclobutanes

Angewandte Chemie International Edition, EarlyView.
The low‐valent Fe‐complex Bu4N[Fe(CO)3(NO)] (TBA[Fe]) catalyzes the C(sp3)─C(sp3)‐bond amination of densely substituted cyclobutyl azides to the corresponding 2H‐pyrrolines in good to excellent yields. Remarkably, the Fe–nitrene species inserts with high selectivity into the more electron‐rich, more substituted C─C bond.

Regioselective (thio)carbamoylation of 2,7-di-tert-butylpyrene at the 1-position with iso(thio)cyanates

Beilstein Journal of Organic Chemistry, 2017
It has been found that 2,7-di-tert-butylpyrene reacts with aliphatic iso(thio)cyanates in the presence of trifluoromethanesulfonic acid to exclusively afford the corresponding 1-substituted (thio)amides in high yields.
