2-Alkyl/arylimino-5-carbethoxythiazolidin-4-ones: A new synthon for the synthesis of spiro and fused ring heterocycles: Part I
Chande, Madhukar S.,Ambhaikar, Shireesh B.
, p. 373 - 376 (2007/10/03)
The title compounds 3 have been synthesised by the interaction of thiocarbamide (2) with diethylbromomalonate (1). The reaction of 3 with hydrazines affords 2-arylimino-2,3,4,5-tetrahydropyrazolo[3,4-d]-thiazol-6(H)-ones (4). Bromination of 3 affords 5-br
