Practical Multigram Synthesis of 3,3,3',3'-Tetramethyl-1,1'-spirobisindane-5,5'-diamino-6,6'-diol
摘要:
with a spirobisindanemoiety have been developed. One of the key monomers is3,3,3',3'-tetramethyl-1,1'-spirobisindane-5,5'-diamino-6,6'-diol (6) as shown in Scheme 1. A few known syntheticmethods of 6 are a direct nitration of 3,3,3',3'-tetramethyl-1,1'-spirobisindane-6,6'-diol (2) with nitric acid followed byreduction using HCO
