Abstract:
N,N-Dialkyl-N′-chlorosulfonyl chloroformamidines 1 underwent regioselective reactions with the 1,3-NCC bis-nucleophilic 1H-benzimidazole-2-acetonitriles 4 and related compounds to produce benzo[4,5]imidazo[1,2-b][1,2,6]thiadiazine dioxides 6, 9, 12, and 14, representatives of a new ring system. Reaction of dichlorides 1 with trifluoroacetyl derivative 16 afforded benzo[4,5]imidazo[1,2-c]pyrimidines 19 and 20. An N-acyl and some N-alkyl derivatives of benzimidazo-thiadiazines 6 were prepared to demonstrate the potential of this new ring system as a novel scaffold for synthetic and medicinal che

Abstract:
A series of N-(4-(benzyloxy)benzylidene)-2-(arylimino)-6-(phenylimino)-3,6-dihydro-2H-1,3,5-thiadiazin-4- amine derivatives (4a-d) have been synthesized by condensation of 1-(N-4-(benzyloxy) benzylidenecarbamimidoyl)-3-arylthiourea (3a-d) with phenyl isocyanodichloride. Interaction of 1- carbamimidoyl-3-arylthiourea (2a-d) and p-benzyloxy benzaldehyde yielded (3a-d). Monoacetyl (5b) and mononitroso (6b) derivatives were also synthesised by substitution of hydrogen atom of cyclic –NH- of 4b on treatment with acetic anhydride and sodium nitrite respectively. Further, 4b upon boiling with 5% aque
