The reactive intermediate generated by the addition of alkyl isocyanides to dialkyl acetylenedicarboxylate was trapped by 6- quinolinol to produce highlyfunctionalized 4H-chromenes in fairly good yields.
An expedient,synthetic method to fused polycyclic derivatives of isoquinoline is described via tandem reaction of isoquinoline,dialkyl acetylenedicarboxylates and dialkyl chloromalonate.
The reaction between 2-aminobenzothiazole with dialkyl acetylenedicarboxylates in the presence of isocyanides,leads to functionalized azadienes in good yields.
An effective route to 5-vinylated and N-vinylated benzo[d]oxazole-2（3H）-thiones and benzo[d]thiazole-2（3H）-thiones is described via reaction of acetylenic esters and benzo[d]oxazole-2-thiol and benzo[d]thiazole-2-...An effective route to 5-vinylated and N-vinylated benzo[d]oxazole-2（3H）-thiones and benzo[d]thiazole-2（3H）-thiones is described via reaction of acetylenic esters and benzo[d]oxazole-2-thiol and benzo[d]thiazole-2-thiol in the presence of 15 mol%of isoquinoline.展开更多
