Synthesis of 2H-pyrano[2,3-b]quinolines. Part I
Cziaky,Sebok
, p. 701 - 705 (2007/10/02)
3,4-Dihydro-2H-pyrano[2,3-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 novel antihypertensive agent Cromakalim (1).
