Stable ruthenium olefin metathesis catalysts bearing symmetrical NHC ligands with primary and secondary: N -alkyl groups

Four novel stable Hoveyda-Grubbs-type catalysts containing N,N′-dineopentyl- and N,N′-dicyclohexyl-substituted N-heterocyclic carbene (NHC) ligands with syn and anti phenyl groups on the ring backbone were synthesized and fully characterized. The catalytic potential of these complexes was investigated in metathesis reactions of both standard and renewable substrates. Compared to the Hoveyda-Grubbs second generation catalyst (HGII), all of the new catalysts showed high performances in most of the examined metathesis transformations. In particular, N,N′-dicyclohexyl catalysts gave improved results in the challenging ring-closing metathesis (RCM) reaction to form tetrasubstituted olefins, while catalysts with neopentyl N-groups were found to be more active and Z-selective in cross-metathesis (CM) reactions. Modest enantioselectivities in the asymmetric ring-closing metathesis (ARCM) of achiral trienes with different steric hindrance were observed in the presence of catalysts bearing chiral C2-symmetric NHC ligands.

Direct reductive coupling of secondary amides: Chemoselective formation of vicinal diamines and vicinal amino alcohols

We report the first one-pot reductive homocoupling reaction of secondary amides and cross-coupling reaction of secondary amides with ketones to give secondary vicinal diamines and amino alcohols. This method relies on the direct generation of α-amino carb

Zn-mediated catalytic photoreduction of aldimines. One-pot synthesis and separation of meso and d,l C2 symmetrical diamines

A new one-pot method for the synthesis and selective separation of 1,2-diamines is reported. The methodology, which involves the photoreduction of imines using catalytic amounts of zinc as a photosensitizer, allows the direct preparation and separation of meso and d,l compounds on a multigram scale.

Reductive coupling of aromatic aldehydes and imines by the low valent titanium species generated in the reaction of TiCl4 with Et3N

Aromatic aldehydes and imines are converted to the corresponding diols and diamines using the low valent titanium species generated by the reaction of TiCl4 with triethylamine.
