3,5-Dimethoxy-α-methylstyrene, which originates from acidic cleavage of the 3,5-dimethoxy-α,α-dimethyl-benzyl-oxycarbonyl residue, an amino protecting group in peptide synthesis, easily dimerizes in solution to 1,3,3-trimethyl-1-(3,5-dimethoxy)-phenyl-5,7-dimethoxyindan in the presence of trifluoroacetic aciEd.
3,5-二甲氧基-α-甲基苯乙烯源自 3,5-二甲氧基-α,α-二甲基苄氧羰基残基(肽合成中的氨基保护基)的酸性裂解,在三氟乙酸的存在下,很容易在溶液中二聚为 1,3,3-三甲基-1-(3,5-二甲氧基)-苯基-5,7-二甲氧基茚满。
