摘要:	Upon photolysis in tetrahydrofuran, dimethyl 2-diazo-6-oxo-2,6-dihy-droazulenc-l,3-dicarboxylate afforded a crown-type origomerized cyclic ether in very low yield, but the major products were the C-H insertion products such as 2,6-disubstituted azulenedicarboxylate, whereas methyl 3-cyano-2-diazo-6-oxo-2,6-dihydroazulene-1-carboxylate gave, similar to 1,3-dicycano-2-diazo-2,6-dihydroazulen-6-one, oligomeric crown ethers predominantly, suggesting that a steric factor played a crucial role in their formations.
