Abstract
Diastereomeric mixtures of tricyclic 3-styrylpyrazolines have been prepared by the reaction of 3-cynnamylidenechroman-4-ones and their 1-thio analogs with hydrazine in hot acetic acid or propionic acid solutions. The diastereomeric mixtures were separated by column chromatography to obtain the pure diastereomers. The elucidation of their structure and stereochemistry and complete 1H and 13C assignments have been performed by a combination of various one- and two-dimensional NMR experiments.
