Notes:
Three-component reactions of 1 with pyridazine or phthalazine afforded the 1,2-dihydro derivatives 2a and 2b, respectively. A similar reaction of 1 with phthalazine performed in aqueous NaOH led to the formation of pseudobase 3. The latter compound proved to be an excellent substrate for the preparation of a series of novel 1,2-dihydrophthalazine derivatives 4a-c, 5 as well as 6a-b by reactions with a variety of active methylene compounds.
