Methods and compositions are provided for efficiently preparing and manufacturing pentostatin. Also provided are novel precursors of pentostatin pentostatin analogs and derivatives. In one aspect of the invention a method is provided for total chemical synthesis of pentostatin via a route of heterocyclic ring expansion. For example a heterocyclic pharmaceutical intermediate for drugs such as pentostatin e.g. the diazepinone precursor can be obtained efficiently through a ring expansion of an O-C...
