✦ Synopsis

Due to the interest in the conformation 192 of the ergot alkaloids the 'H-NMR spectra of 1, 3 and the 13C-NMR spectra of 1, 2, Q, 5 were recorded and the conformations determined. The synthesis of 1, 2 and 3 was described -334 elsewhere. 1 H-NMR. The C-and D-ring protons were assigned by means of decoupling
