A convenient synthesis of 2-arylidene-5H-thiazolo[2,3-b]quinazoline-3,5[2H]-diones and their benzoquinazoline derivatives

Various 5H-thiazolo[2,3-b]quinazoline-3,5[2H]-diones (7a,b), 2-arylidene-5H-thiazolo[2,3-b]quinazoline-3,5[2H]-diones (9a-o) and 2-arylidene-5H-thiazolo[2,3-b]benzoquinazoline-3,5[2H]-diones (12a,b) have been synthesized via simple and efficient methods.

Synthesis of some new derivatives of thiazolo[4,3-b]- and thiazolo[2,3-b]quinazolone

The new 5H-thiazolo[4,3-b]quinazoline-3,5(1H)-diones 3, 4a-c, 5a-c and 5H-thiazolo[2,3-b]quinazoline-3,5(2H)-diones 9a-c, 11a-c were prepared by reaction of anthranilic acid with the 2-thiazolidinone-4-thione derivatives 1b, 6a-c, 7a-c and the 5-substitut
