Enantioselective Access to 3-Azabicyclo[3.1.0]hexanes by (CpRhIII)-Rh-x Catalyzed C-H Activation and Cp*Ir-III Transfer Hydrogenation

Nicolai Cramer, Dan Forster, Coralie Danielle Annick Duchemin

Rigid saturated nitrogen-containing scaffolds such as 3-azabicyclo[3.1.0]hexanes are very important and frequently occurring motifs in biologically active compounds. We disclose a flexible two-step protocol for their efficient and selective access. A tailo ...

One-step access to N-enoxyimides by gold-catalysed addition of N-hydroxyimides to terminal alkynes

Nicolai Cramer, Coralie Danielle Annick Duchemin

N-Enoxyimides have become attractive substrates for novel catalytic transformations, yet their tedious multi-step synthesis hampers full exploitation of their synthetic potential. We report a gold(I)-catalyzed protocol to access N-enoxyimides from simple a ...

Chiral cyclopentadienyl Rh-III-catalyzed enantioselective cyclopropanation of electron-deficient olefins enable rapid access to UPF-648 and oxylipin natural products

Nicolai Cramer, Coralie Danielle Annick Duchemin

Chiral cyclopentadienyl Rh-III complexes efficiently catalyze enantioselective cyclopropanations of electron-deficient olefins with N- enoxysuccinimides as the C1 unit. Excellent asymmetric inductions and high diastereoselectivities can be obtained for a w ...
