                                摘要:
                                A regioselective access to both alpha- and gamma-folic acid conjugates derived from archaeal lipid analogues is described. The synthetic approach is based on conveniently protected glutamates that led first to alpha- and gamma-glutamate derivatives. The final reconstruction of the folic acid moiety was achieved through the reaction of a protected/activated pteroate followed by a simple deprotection step. These alpha- and gamma-folic acid conjugates Would permit to establish the importance of a regiocontrolled introduction of folic acid on the folic acid/folate receptor interaction in the case of a targeted drug/gene delivery.
