3-b]quinolines 5a-e and 2H-pyrano[2,3-b]quinolines 10a-c were synthesised starting from the appropriate ω-chloro-n-valeroylanilides 2a-e. Compounds 10a-c were transformed to analogs of the novelantihypertensiveagentCromakalim (1).
从合适的ω-氯-n-戊酰苯胺开始合成3,4-二氢-2 H-吡喃并[2,3 - b ]喹啉5a-e和2 H-吡喃并[2,3 - b ]喹啉10a-c。2a-e。将化合物10a-c转化为新型降压药克罗卡林(1)的类似物。
