REACTIONS WITH SULFOLENES II. "CRISS-CROSS' ADDITION OF ALDAZINES: SYNTHESIS OF SEVERAL NEW ANNELATED PYRAZOLOPYRAZOLE DERIVATIVES
Ghabrial, Sami S.
, p. 17 - 22 (2007/10/02)
New annelated pyrazolopyrazole derivatives were synthesised via the reaction of aryl aldazines with sulfolene and treatment of the resultant products with different reagents.Structures were established using elemental analysis and spectral data. Key words: Aldazines; sulfolene; criss-cross cycloaddition; pyrazoles; bis-thiazolopyrazoles.
