The reactions of guaiazulene with 2, 4, 6-trichloro-1, 3, 5-triazine and 3, 6-dichloropyridazine gave triazinyl- and pyridazinylguaiazulenes in 52% and 60% yields, respectively. The reduction of the triazinyl derivative with sodium borohydride yielded a ring-opening product. But, the same reaction of the pyridazinyl derivative with sodium borohydride yielded an unreduced product which was cyclized between β-carbon of pyridazine ring and 4-methyl group in guaiazulene.
