摘要

The synthesis of 2-(CH30, CH3, C1, Br, I, CN) and 3-substituted (CH30, CH3, CHsS, Br, COCH3, CN, NOz) derivatives of 2-(l-azulyl) ethanol (l-OH) and 1-OAc by combining conventional procedures are reported. A method for the protodeamination of diethyl 2-amino- 6-bromoazulene-l, 3-dicarboxylate(3) to diethyl 6-bromoazulene-1, 3-dicarboxylate (7) in 93% yield using p-hydroquinone as in situ reducing agent of the intermediate diazonium ...
