## Abstract The two new phthalideisoquinoline hemiacetals rac‐egenine (3) and rac‐corytensine (4) are prepared by stereoselective DIBAL reduction of rac‐bicuculline (1) and rac‐adlumidine (2), respectively. The identity of egenine (3) with decumbensine as well as of corytensine (4) with epi‐α‐decum

✦ Synopsis
The molecular conformation of phthalideisoquinoline derivatives was studied by 'H NMR methods. For the qualitative determination of the conformational preferences, proton relaxation times, 1D and 2D NOE experiments were applied. Our proposals were supported by the calculation of the effects of ring currents.

## Abstract ^1^H and ^13^C data are presented for eleven 1,3,5‐triazaadamantane derivatives. Ring protonation produces a decrease in ^1^H screening and the opposite effect in the corresponding ^13^C spectrum. The trisaryl substituted compounds appear to exist as a single isomer with diequatorial an
A model of the Actinomycin structure is derived on the basis of theoretical calculations taking into account available IK, NMR and x-ray experimental data. This model contains two intercycle hydrogen bonds and accounts for all the experimental evidence.
