A four-step domino Knoevenagel–hetero-Diels–Alder reaction
摘要:
A new, catalyst-free, domino Knoevenagel-hetero-Diels-Alder elimination oxidation reaction is reported. 5-Aryl-2H,6H-chromeno[4',3':4,5]thiopyrano[2,3-d][1,3]thiazol-2-ones are formed in moderate to good yields via reaction of 2-(3-aryl-3-chloro-2-propenyloxy)benzaldehydes with 4-thioxo-1,3-thiazolidin-2one.
