dichloromethane. The two copper atoms in complex 1 are bridged by two L 1 ligands in a trans disposition; the naphthyridine nitrogen atoms bridge two copper centers and the carbonyl oxygen atoms occupy sites trans to the Cu···Cu vector. The metal···metal distance is 2.4594(6) A. In contrast, in complex 2, each of the two L 2 ligands bind to the two copper atoms through one naphthyridine nitrogen, a deprotonated amide

reduction of ferrocenyl cyclopropylimines to the corresponding amines triggers a facile oxidative ring-opening to yield the formal four-electron oxidation products: N-ferrocenylmethyl β-hydroxyamides. This process is believed to proceed via generation of a ferrocinium ion in the presence of air, leading to facile formation of a distonic radical cation that is ultimately trapped by oxygen.

components from previous inhibitors. In conjunction with extensive structure–activity studies, several highly potent and selectiveinhibitors of nNOS were discovered. X-ray crystallographic analysis reveals that these type II inhibitors utilize the same hydrophobic pocket to gain strong inhibitory potency (13), as well as high isoform selectivity. Interestingly, select compounds from this series (9) showed

repurposed for catalyzing abiological carbene transfer reactions. Herein, we rationally designed an engineered variant of nitrophorin 2 (NP2)─a nitric oxide transport hemoprotein─that catalyzes olefincyclopropanation with high activity and stereoselectivity. Being a β-barrel protein, the engineered NP2 variant showed a unique substrate preference, in contrast to the mainstream α-helical carbene-transfer
