✦ Synopsis

Recently the use of two new shift reagents, Eu(fod)3 and Pr(fod)3, have been reported by Rondeau and Sievers. * The advantage of these as shift reagents is due to their relatively high solubility in nonalcholic solvents and to the fact that neither Eu(fod)3

## Abstract The isomeric tricyclo[4.4.1.1^2,5^]dodecan‐11‐ols have been synthesized from the (6+4) cycloaddition product of tropone with cyclopentadiene. The configuration and conformation of each isomer was determined from the proton shift gradients induced in the olefinic proton signals in the ^1

An assignment of relative configurations has been achieved for the diastereomeric racernates(lR2R,lS2S) and (1R2S, 1S2R) of 3,3-dimethyl-l,2-diphenylbuta~-l-ol through the comparative analysis of the respective chemical shifts induced by Eu(fod), in the 'H and '"C NMR spectra, and the corresponding
