The article contains the following contents:
The synthesis, optical resolution through derivatization, characterization, and utilization of a new helical bis(phosphinite gold)complex derived from 2,15-bishydroxy[6]helicene (HELIXOL) are described. By using an efficient cobalt catalyst, neither irradiation nor high catalytic loading was required to access the helicene of interest. The latter was phosphorylated to afford a new chiral ligand that was studied. Especially, treatment with AuCl(SMe2) gives a dinuclear gold complex that was used in cycloisomerization reactions. The experimental procedure involved many compounds, such as (1S)-4,7,7-Trimethyl-3-oxo-2-oxabicyclo[2.2.1]heptane-1-carbonyl chloride(Chunks or pellets) (cas: 39637-74-6) .
(1S)-4,7,7-Trimethyl-3-oxo-2-oxabicyclo[2.2.1]heptane-1-carbonyl chloride(Chunks or pellets) (cas: 39637-74-6 Related Products of 39637-74-6) is used as a resolving agent for alcohols as the diastereomeric esters by crystallization or chromatography and as a chiral derivatization reagent for determination of enantiomeric excess of alcohols and amines.
