F. Martinet et al., REGIOSELECTIVE HYDROLYSIS OF COCAINE AND A CONVENIENT ACYLATION PROCEDURE BY BENZOYLECGONINE, Synthetic communications, 27(19), 1997, pp. 3485-3490
Regioselective hydrolysis of cocaine led, according to the reaction co
nditions, either to benzoylecgonine or to ecgonine methyl eater. Acyla
tion with benzoylecgonine was readily achieved when benzotriazolyloxyt
risdimethylaminophosphonium (BOP) was used as a coupling agent.
