2-Methoxyquinoline 3,4-quinodimethane 4, X = OMe, can be generrated from the quinoline 3,4-fused dihydrothiophene S,S-dioxide 23 and trapped with dienophiles but 4-methoxyquinoline 2,3-quinodimethane 3, X = OMe, cannot be obtained from the corresponding sulfone. Quinolone 2,3- and 3,4-quinodimethanes are readily available from the sulfones 9 and 19 respectively
2-甲氧基喹啉3,4-喹二甲烷4(X = OMe)可从喹啉3,4-稠合的二氢噻吩S,S-二氧化物23生成,并被亲二烯体捕获,但4-甲氧基喹啉2,3-喹二甲烷3(X = OMe)不能从相应的砜中获得。喹诺酮2,3-和3,4-喹二甲烷很容易分别从砜9和19获得
