For example, cis- and trans-double bonds, endo- and exo-substitution on bicyclic ring systems, and compounds containing multiple stereogenic centers with different relative configurations are considered to be diastereomers. The term “diastereomer” refers to any member of this set of compounds. In...
miembros dímeros en estado sólido, pero difieren en estereoquímica: el anillo de ocho miembros adopta una conformación en forma de tubo y tiene grupos cis y también grupos THF ligandos donde el anillo tiene forma de silla y los grupos de bromo y los ligandos de THF son trans....
Dinuclear and polymer complexes of 4-phenylpyridine (4-phpy), pyazine (pyz), and 4,4′-bipyridine (4,4′-bpy) were prepared by using cis-[Rh2(4-Me-pf)2(O2CR)2] (4-Me-pf- =N,N’-bis(4-methylphenyl)formamidinate anion; R = CF3 and CMe3) as precursor dinucl
Not a matter of preference: The polyketide borrelidin contains both a trans and a cis double bond. The corresponding dehydratases in the polyketide synthase are found to have identical preferences for thioester substrates in vitro and to generate trans double bonds, undermining the idea that cis ...
