Toward the creation of NMR databases in chiral solvents for assignments of relative and absolute stereochemistry: scope and limitation.

[structure: see text] Three additional NMR databases, 1-3, in a chiral solvent are presented. The C.21-C.38 portion of oasomycin A is used to demonstrate the scope and limitation of the universal NMR database approach in a chiral solvent for assignment of relative and absolute stereochemistry without degradation and/or derivatization.
