Conclusions
-
1.
The synthesis of traumatoic (2E-dodecanedioic) acid from 1,12-dodecanedioic acid via the diethyl ester of 2-bromododecanedioic acid was proposed.
-
2.
The diesters of α-bromodicarboxylic acids were dehydrobrominated to the diesters of α,β-unsaturated dicarboxylic acids by using either NaHCO3 in HMPA or Li2CO3 in DMF.
