Abstract: B mesons have been reconstructed in five decay channels of the type B$\rightarrow$ D$^ 0$ $\pm$n$\pi$(n=1,2,3) using data accumulated by the ARGUS experiment at the e+e− storage ring DORIS II at DESY. In total, we find 40 neutral B mesons above a background of 15±6 events with a mass of (5278.2±1.0±3.0) MeV/c2 and 32 charged B mesons above a background of 17±6 events with a mass of (5275.8±1.3±3.0) MeV/c2. The decays B$^0$ D$^*$$^+$$\pi -$$\pi -$$\pi +$ and B$^-$ $\rightarrow$D$^*$$^+$$\pi -$$\pi -$$\pi$$^0$ have been observed for the first time. We find substantially smaller branching ratios for the decay modes and than previously published by the CLEO collaboration.
