Abstract: We report herein the enantioselective photoinduced Nazarov reaction using a relay strategy of an electrocyclization, followed by parallel kinetic resolution (PKR). No enantioselectivity was observed during electrocyclization due to weak coordination between chiral ligands and… read more here.

Abstract: A one-pot tandem Diels-Alder/Nazarov reaction of 1-aryl-3-(trimethylsilyl) ynones has been achieved to generate carbo- and heterocyclic fused ring systems in good to excellent yields. The β-silyl effect is instrumental in accessing this otherwise challenging cascade… read more here.
