Fused phosphono substituted O-, and N-heterocycles via condensative cyclisation reactions of α-phosphonyl carbanions with 4-thiazolidinones

Phosphono substituted-thiazolones 5a,b together with fused phosphono-pyran-5-ones 9a,b and the diolefins 8a-d were regioselectively prepared in reasonable yields from the reactions of 5-arylidene-4- thiazolidinones 1a,b with phosphonoacetates 2a,b. Conversely, Michael addition products 11a,b (～30%) along with the phosphono substituted-thiazole derivatives 12a,b (～33%) were obtained from treating 1a,b with cyanomethylenephosphonates (2c). The reactions of 1a,b with vinylphosphonate 2d proceeded with phase-transfer catalysis, yielding the corresponding 2-thioalkyl-derivatives 14a,b and phosphonates 13a,b.
