Y. Kobayashi et al., Toward creation of a universal NMR database for the stereochemical assignment of acyclic compounds: The case of two contiguous propionate units, ORG LETT, 1(13), 1999, pp. 2177-2180
Using triol 1 as a representative example of natural products containing tw
o contiguous propionate units, C-13 and H-1 NMR databases for the stereoche
mical assignment of acyclic compounds have been created. Chemical shift inc
rements due to the presence of additional functional groups as well as solv
ent effects are discussed.
