[Enantioselective synthesis of anthracyclines]
1Institut Curie, CNRS URA 1387, Paris.
Abstract:
Enantioselective synthesis of new anthracyclinones is reported by chiral pool synthesis, using readily available lactose or glucose as starting materials. Glycosidation of such aglycones with various carbohydrates, including or not an amino function, led to anthracyclines endowed with significant antitumor activity but having some cross-resistance with daunorubicin and doxorubicin. Lowered cross-resistance was observed when the anthracycline beared an alkyl side-chain at C-9 and a morpholinyl residue at C-4'.

Preparation of 1° Amines: Azide Synthesis
Azide ions act as good nucleophiles and react with unhindered alkyl halides to form alkyl azides. Alkyl azides do not participate in further nucleophilic substitution reactions, thereby eliminating the chances of polyalkylated products. Alkyl azides are reduced by hydride-based reducing agents, like lithium aluminum...
