Concise Total Synthesis of (?)-Vermiculine through a Rhodium-Catalyzed C2-Symmetric Dimerization Strategy
A short and efficient synthesis of the C2-symmetric antibiotic (?)-vermiculine by utilizing an enantioselective catalytic one-step dimerization methodology as key-step to construct the core structure is reported. The late-stage modifications feature a double metathesis homologation followed by a double Wacker-type oxidation. These key-steps allowed the synthesis of vermiculine in only seven steps, starting from commercially available building blocks.

Pyridine-oxazoline and quinoline-oxazoline ligated cobalt complexes: Synthesis, characterization, and 1,3-butadiene polymerization behaviors
A series of cobalt complexes supported by pyridine-oxazoline (Pyox) and quinoline-oxazoline (Quox) were synthesized. Determined by single crystal X-ray crystallography, complexes 6a and 7c adopted distorted octahedron and trigonal bipyramid geometries, re

QUINOLINE-OXAZOLINE COMPOUNDS AND THEIR USE IN OXIDATION SYNTHESIS
A quinoline-oxazoline compound having the formula: where one of X1 and X2 is N and the other is C and one of R1, R2 and R3 is Z wherein Z is an oxazoline radical having the formula such that when X1 is N R2 is Z and R1 is absent, and when X2 is N either R1 or R3 is Z and R2 is absent. R1 and R3 through R12 are independently H or a pendant moiety which does not interfere with coordination of either N in the quinoline compound with a coordination center. These compounds can be complexed with a suitable coordination center such as catalytically active palladium and can be highly useful in catalytically oxidizing alkenes with high regioselectivity.

Catalyst-controlled Wacker-type oxidation of protected allylic amines
On the contrary: Utilizing the [Pd-(quinox)]-TBHP catalyst system, protected allylic amines were oxidized with high selectivity for the methyl ketone product. This is contrary to the results obtained by the substrate-controlled Tsuji-Wacker oxidation, which highlights the catalyst-controlled system presented here (see scheme). A variety of N-pro-tecting groups undergo selective oxidation with high ketone selectivity. TBHP = tert-butylhydroperoxide.
