Meio-epoxides undergo a ring-opening reaction with aromatic amines in the presence of a chiral metal-organic framework catalyst Zn2(L)(H20)2(A,A -dimethylacetamide)4 where L, [(S)-6,6 -dichloro-2,2 -diethoxy-1,T-binaphthyl-4,4 -bis(5-isophthalic acid)] is an organic linker between the zinc clusters Yields of the a-hydroxyamine ranging i from 70 to 95% with 62-89% ee were obtained using CM-stilbene epoxide and aniline. Lower yields and much lower ee values were found when different substituents were on the stilbene epoxide or the aniline.

The metal centers in many important MOFs are zinc(II) with the IRMOFs (isoreticular metal-organic frameworks) and ZIFs (zeolitic imidazolate frameworks) being the two most important series. Zn (/= 5/2) is the only stable NMR-active isotope of zinc. Unfortunately, it has a small gyromagnetic ratio...
