Reactions of 1,1a-dihydro-1,2-diarylazirino[1,2-a]quinoxalines with dimethyl 1-cyclobutene-1,2-dicarboxylate gave mixtures of the 1,2-fused-4,5-dihydro-1H-azepines along with the 1:1 adducts that were converted to the azepines upon treatment with Pd-C.
1,1a-二氢-1,2-二芳基氮杂喹啉[1,2-a]的反应与二甲基1-环丁烯-1,2-二羧酸酯,得到1,2-融合的4,5-二氢-1H-氮杂庚烯的混合物,以及1:1加合物,后者在与Pd-C处理后转化为氮杂庚烯。
