摘要

Various novel 3, 5a, 6, 11b-tetrahydro-2H, 5H-chromeno [4′, 3′: 4, 5] thiopyrano [2, 3-d][1, 3] thiazol-2-ones were synthesized in 60–80% yields via domino-Knoevenagel–hetero-Diels– Alder reactions of 4-thioxo-1, 3-thiazolidin-2-one with 3, 7-dimethyl-6-octenal, 2- allyloxybenzaldehydes and 2-formylphenyl (E)-3-aryl-2-propenoates with base catalysis. The possibility of stereo-and regioselective cycloaddition was investigated.
