1H-1H Long range couplings in fused cyclopropanes. NMR spectral assignment and conformation of 17,18-cyclosteroids

Mostrar todas las versiones(2)

1H-1H NMR couplings through four bonds ( 4JH-H) involving cyclopropane hydrogens were calculated for model compounds by semiempirical methods and used for the 13C and 1H NMR spectral assignment of 17,18-cyclosteroids. The couplings (4JHH) between cyclopropyl and non-cyclopropyl hydrogens follow an a...
