We show that the CKM phase $2 \beta+\gamma$ can be extracted from measurement of the time dependent rates in the decays $\bar{B}^0 \to D^{(*)\pm} M^\mp$ and $B^0 \to D^{(*)\pm} M^\mp$, where $M=a_0$, $\pi(1300)$, $b_1$, $a_2$, $\pi_2$, $\rho_3$. These channels have a large asymmetry between decays of $\bar{B}^0$ and $B^0$ into the same final state. Even though the branching ratios are small, their sensitivity to $\gamma$ can be competitive with decays into $D^{(*)}$ and $(\pi,\rho,a_1)$.
