“Non-conventional” synthetic method has shown broad applications as a very efficient way to accelerate the course of many organic reactions, producing high yields, higher selectivity and lower quantities of side products consequently easier work-up and purification of the products.  One-pot two-component condensation of 1-formamidino-5-ethylformamidonothicarbamide (llla) with various isocyano-dichlorides(Xla-g) were carried out in presence of lemon juice as a biocatalyst respectively to synthesize a novel series of 2-substitutedimino-4-amino-6-ethylformamidino-1,3,5-thiadiazines (Xlla-g) which are neither to unknown. The structures were confirmed by conventional chemical characterization, elemental analysis and spectral studies.
