benzocyclobutene-based α-amino acid derivative, ethyl 5-acetamido-2,4,5,6-tetrahydro-1H-cyclobuta[f]indene-5-carboxylate is synthesized via coupling of a benzocyclobutene-derived dibromide with ethyl isocyanoacetate as the key step, followed by hydrolysis and subsequent acetylation. This methodology is generalized in order to prepare various linearly and angularly fused indane-based α-amino acid derivatives. α-amino
通过将苯并环丁烯衍生的二溴化物与异氰基乙酸乙酯偶联,合成了基于苯并环丁烯的α-氨基酸衍生物5-乙酰氨基-2,4,5,6-四氢-1 H-环丁[ f ]茚5羧酸酯作为关键步骤,然后进行水解和后续的乙酰化反应。这种方法是为了制备各种线性和角度稠合茚满基-α广义-氨基酸衍生物。 α-氨基酸-[2 + 2 + 2]环加成-茚满基α-氨基酸-苯并环丁烯-异氰基乙酸乙酯-面向多样性的方法
