A trimer of noracronycine has been isolated from the mixture obtained after treating
noracronycine with methanolic hydrochloric acid, and its structure deduced by partial
synthesis of the dihydro derivative, and examination of the 1H NMR spectral parameters in comparison with those obtained for the two dimers reported
previously.
