Room temperature palladium-catalyzed cross coupling of aryltrimethylammonium triflates with aryl Grignard reagents.
Aryltrimethylammonium triflates and tetrafluoroborates were found to be highly reactive electrophiles in the Pd-catalyzed cross coupling with aryl Grignard reagents. The coupling reactions proceed atExpand

DYKAT of vinyl aziridines: total synthesis of (+)-pseudodistomin D.
A concise total synthesis of (+)-pseudodistomin D was developed. The absolute stereochemistry was established through a dynamic kinetic asymmetric cycloaddition of an isocyanate to a vinyl aziridine.Expand
