Chen, Jing-Xing published the artcileSynthesis and Chiroptical Properties of Double-Helical (M)- and (P)-o-Oligophenylenes, Safety of ((1S,4R)-7,7-Dimethyl-2-oxobicyclo[2.2.1]heptan-1-yl)methanesulfonyl chloride, the publication is Organic Letters (2015), 17(17), 4296-4299, database is CAplus and MEDLINE.
All of the M and P isomers of optically pure oligophenylenes with 6, 8, 10, and 12 Ph rings were synthesized and fully characterized. The Suzuki cross-coupling reaction has been revealed to be a viable strategy in the syntheses of tetraphenylene derivatives, which, together with the copper-mediated oxidative cross-coupling reaction, were employed in the quest for the oligophenylenes [e.g., (S,S)-I + (M)-II â?(M)-III (5%) + (M)-IV (6%) + (M)-V (9%) using t-BuLi/CuCl2]. X-ray diffraction anal. in combination with sp. rotation and CD spectroscopy unambiguously identified the unique covalent double-helical frameworks of these oligophenylene mols.
Organic Letters published new progress about 21286-54-4. 21286-54-4 belongs to chlorides-buliding-blocks, auxiliary class Chiral,Chloride,Sulfonyl chlorides,Aliphatic cyclic hydrocarbon,Ketone, name is ((1S,4R)-7,7-Dimethyl-2-oxobicyclo[2.2.1]heptan-1-yl)methanesulfonyl chloride, and the molecular formula is C10H15ClO3S, Safety of ((1S,4R)-7,7-Dimethyl-2-oxobicyclo[2.2.1]heptan-1-yl)methanesulfonyl chloride.
