## Abstract Synthesis of the linear and angular furoquinolinβ4βone derivatives 6 and 12 was performed, using nitrobenzofurans 3 and 9 as key intermediates. These compounds were reduced to the corresponding aminobenzofurans 4 and 10, which were condensed in two steps to yield, the linear furoquinoli
## Abstract The synthesis of [1,4]dioxino[2,3β__c__]quinolines and [1,4]dioxepino[2,3β__c__]quinolines with restrained conformation of the piperidine ring, which represent 1,2,3,4βtetrahydroquinolines containing two heteroatom substituents at positions 3 and 4, is described. In addition, the applic
