Yldrm, Muhammet,Dürüst, Yaar
experimental part, p. 3209 - 3215 (2011/05/30)
1,3-Dipolar cycloaddition of in situ generated C,N-diaryl nitrilimines to 2-methyl-2-vinyl oxirane gives rise to the regioselective formation of novel 5-(2-methyloxiranyl)-4,5-dihydropyrazole derivatives in moderate to good yields. The structures and ster
