Reimlinger, Hans; Vandewalle, Jan J. M.; King, Geoffrey S. D.; Lingier, Willy R. F.; Merenyi, Robert published the artcile< 1,5-Dipolar cyclizations. III. Condensed triazoles from conjugated nitrilimines. Structure and stability of the products from the reaction of N-acylated cyclic amidrazones with thionyl chloride>, Application of C19H34O2, the main research area is dipolar cyclizations; cyclizations dipolar; acyl amidrazones reaction thionyl chloride; amidrazones acyl reaction thionyl chloride; thionyl chloride reaction acyl amidrazones; triazolopyridines; pyridines triazolo; oxathiadiazoles; isoquinolines thiatriazolo structure; thiatriazoloisoquinolines structure; crystal structure thiatriazoloisoquinolines.
Treatment of 2-[2-(RCO-substituted)hydrazino]-5,6-(R1R2-disubstituted)pyridines with SOCl2 gave 5-(R-substituted)-3-[5,6-(R1R2-disubstituted)-2-pyridyl]-3H-1,2,3,4-oxathiadiazole S-oxides (I) [where R = Me, Ph, o-O2NC6H4, 2-pyridyl, or 4-pyridyl; and R1, R2 = H or (mono)Cl]. On thermolysis, I yielded the corresponding 3,5,6-(RR2R1-trisubstituted)-s-triazolo[4,3-a]pyridines (II). Reaction of 1-[2-(RCO-substituted)hydrazino]-3-(R1-substituted)isoquinolines with SOCl2 in HCONMe2-Et3N gave 2-(RCO-substituted)-5-(R1-substituted)-2H-1,2,3,5-thiatriazolo[4,5-a]isoquinoline S-oxides (III) (where R = Me, Ph, PhCC, or o-O2NC6H4 and R1 = H or Cl) or 5-(2-nitrophenyl)-3-(3-chloro-1-isoquinolyl)-3H-1,2,3,4-oxathiadiazole S-oxide (IV). III (R = Me, R1 = Cl) crystallizes in the triclinic space group P1 or P1 ̅with a = 11.528 ± 0.003, b = 8.054 ± 0.002, c = 7.258 ± 0.002 Å, α = 63.22 ± 0.02°, β = 85.26 ± 0.03°, γ = 74.38 ± 0.02°; d. (exptl.) = 1.621 ± 0.005 and d. (calculated) 1.616 for Z = 2. Ir data of III are reported.
