โœฆ Synopsis


The previous paper0 l-3 from thio laboratory describe the synthesis of 213 dihydrofuro(2,3-b)quinolines , and in no cane oould the dihydro compound be dehydrogeaated to the furoquinoline. The poaeibility that 3-vinyl-2-quinolones might oerve aa nece#aary precursor6 for the syntheaie of furo(2,3-b)quinolineo appeared attraative.

## Abstract Synthesis of the linear and angular furoquinolinโ€4โ€one 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

It has been observed' that J-(l'-propenyl)P-quinolonee readily yield 2-methyl-2,3-dihydrofuro(2,3-b)quinolines on treatment with polyphosphorio acid whereas 3-vinyl-2-quinolones do not afford the oorreeponding dihydrofuroquinolines under the same conditions2. In this communication, we report a novel
