We report herein the regioselective synthesis of all-carbon lemniscular nanohoops bis-po-CC and bis-pm-TC by the rational control of ring closures at the different positions of planar chiral tetrasubstituted [2.2]paracyclophane. Topological analyses reveal that bis-pm-TC is topologically chiral while bis-po-CC is topologically …
WebApr 6, 2024 · First of all, a chiral carbon is a carbon which has four different atoms or groups of atoms attached to it. The chiral atom in a molecule makes it optically active. Glucose and fructose are structural isomers. Their molecular formula is ${C_6}{H_{12}}{O_6}$. They both have different parent functional groups. WebCarbon #2 is a chiral center: it has four bonds to other atoms and is tetrahedral, and each of the four things attached to it is different: a hydrogen, a methyl (-CH 3) group, an ethyl (-CH 2 CH 3) group, and a hydroxyl (OH) group.
