DABCO-Promoted three-component regioselective synthesis of functionalized chromen-5-ones and pyrano[3,2-c]chromen-5-ones via direct annulation of α-oxoketene-N,S-arylaminoacetals under solvent-free conditions

An efficient and convergent route to 3-aroyl-4-aryl-2-arylamino-4,6,7,8- tetrahydrochromen-5-ones and hitherto unreported 3-aroyl-4-aryl-2-arylamino-4H- pyrano[3,2-c]chromen-5-ones has been developed by an one-pot three-component domino coupling of α-oxok

Transition-metal-free solid phase synthesis of 1,2-disubstituted 4-quinolones via the regiospecific synthesis of enaminones

Herein, the transition-metal-free economical solid phase synthesis of 1,2-disubstituted 4-quinolones has been developed via the novel regiospecific synthesis of enaminones. Notably, a wide range of enaminones were synthesized via a silica-supported solid-
