Abstract: It was found that brief refluxing of N -hetarylcyclopentano[ d ][1,2,3]triazolines in methanol resulted in the elimination of nitrogen, accompanied by cyclopentane ring opening with the formation of N -hetarylvaleramidines. Amidines containing pyrimidine-2,4-dione ring were… read more here.

Abstract: Phosphorylthioformic acid morpholides can be successfully used as a precursor in the synthesis of complexes of phosphoryl-substituted thiohydrazides with hydrazine and morpholine. The reaction of sterically hindered phosphorylthioformic acid morpholides with hydrazine hydrate proceeds chemoselectively… read more here.
