Photolysis (10 h) of l,3-dimethyl-5-nitro-6-(l-methyl-2-acetophenyli-denehydrazino)pyrimidine-2,4-dione (71b) in acetonitrile gave an excellent yield of 2,6-dioxo-l,3,9-trimethyl-8-azapurine 7-JV-oxide (72). This product was apparently formed by the addition of a photoexcited NO2 group across the exocyclic double bond, followed by rearrangement of the tricyclic (dioxatriaza) product. ... [Pg.160]

Spiro-biscyclam (133) has been prepared by reduction of the spiro-bis(dioxo-cyclam) (131),171 formed from the spiro-octaamine (130) by reaction with diethyl malonate (Scheme 31). A nitroethane/methanal Mannich condensation of the Cu11 compound of (130) formed the spiro-bis(nitro-methyl-cyclam) (132), which reduces to the spiro-bis(amino-methyl-cyclam) compound (134).175...
