proven to be versatile intermediates in organic chemistry. Few diamines, however, can be appended to organic and inorganic supports without modification of the diamine functionality. We report the synthesis of 3,8,11,16-tetrakis-(N-BOC-aminomethyl)-1,2,9,10-tetrathia-cyclohexadecane (2) and 3,8,11,16-tetrakis(aminomethyl)-1,2,9,10-tetrathia-cyclohexadecane tetra-trifluoroacetic acid (3), potential precursors
二胺已被证明是有机化学中的通用中间体。然而,在不改变二胺官能度的情况下,很少有二胺可以被添加到有机和无机载体上。我们报告了3,8,11,16-四-(N -BOC-氨基甲基)-1,2,9,10-四硫代-环十六烷(2)和3,8,11,16-四(氨基甲基)的合成-1,2,9,10四硫-cyclohexadecane四三氟乙酸(3),潜在的前体到1,8-二氨基- 2,7-辛二硫醇(4)。在4的二胺主链内掺入硫醇单元可使该化合物连接到有机和无机支架上。光谱和化学数据表明1,8-双(N-BOC-氨基)-2,7-双(乙酰硫基)辛烷(16)产生了16元的双二硫键2而不是8元环的二硫烷17。
