Cis And Trans

The regioselective synthesis of cis and trans stereoisomers of variously functionalized octahydro[1,2,4]triazolo[4,3-a]quinazolin-5-ones was performed. The 2-thioxopyrimidin-4-ones used in the synthesis reacted with hydrazonoyl chlorides in a regioselective manner to produce the angular regioisomers [1,2,4]triazolo[4,3-a]quinazolin-5-ones rather than the linear isomers [1,2,4]triazolo[4,3-a]quinazolin-5-ones. The synthesis process took place with electronic control. The angular regiochemistry of the products was confirmed by X-ray experiments and two-dimensional NMR studies.

Acetyl Group

Methyl 3-aminothiophene-2-carboxylate reacts readily, in the presence of triethylamine, with hydrazonoyl chlorides (7a - c) to afford good yields of the corresponding N-arylamidrazones (8a - c). The latter acyclic adducts undergo, in the presence of t-BuOK/t-BuOH, cyclocondensation accompanied by elimination of the acetyl group present in 8, to deliver the respective thieno-1,3,4-triazepin- 5-ones 10a - c.
