A synthesis of 9-aminoalkyl-9, 10-dihydro-9, 10-methanoanthracenes (2) is reported. A key intermediate, 9-formyl-9, 10-dihydro-9, 10-methanoanthracene (4), was synthesized from 9-amino-12-hydroxy-9, 10-dihydro-9, 10-ethanoanthracene (3b) by nitrous acid deamination. The amino-alcohol (3b) was synthesized in 5 steps starting from anthracene-9-carbaldehyde.
报告了 9-氨基烷基-9,10-二氢-9,10-甲桥蒽 (2) 的合成。关键的中间体 9-甲酰基-9,10-二氢-9,10-甲桥蒽 (4) 是由 9-氨基-12-羟基-9,10-二氢-9,10-乙桥蒽 (3b) 通过亚硝酸脱氨合成的。氨基醇 (3b) 由蒽-9-甲醛开始,分 5 步合成。
