説明

1-Protected 2(1H)-pyridones are highly useful dienophiles because Diels-Alder reaction of 1-sulfonyl-2(1H)-pyridones gave the synthetic intermediate such as quinoline and isoquinoline derivatives. Acylation of 2(1H)-pyridone bearing a methoxycarbonyl group at the 5 or 6-position with benzoyl chloride having a some functional group (such as bromo, methoxy, nitro) gave 1-benzoylated 2(1H)-pyridone derivatives. Further, the sulfonylation of 3-cyano- and 3-methoxycarbonyl-1(2H)-isoquinolones afforded 2-sulfonylisoquinolone derivative.
