摘要：

A "poor man's" method is how the authors refer to their procedure to separate overlapping cross-peak multiplets in two-dimensional NMR spectra. A homonuclear Hartmann-Hahn coherence transfer precedes a soft-COSY pulse sequence, which enables, for example, the selection of the multiplet of the trans isomer of 1, R = CO2Et, R' = Ph, from the superimposed multiplet of cis and trans isomers (see diagram on the right).
