We study the $\sin2\phi$ azimuthal asymmetry in the $\pi N$ Drell-Yanprocess, when the nucleon is longitudinally polarized. The asymmetry iscontributed by the combination of the Boer-Mulders function and thelongitudinal transversity distribution function. We consider the Drell-Yanprocesses by $\pi^\pm$ beams colliding on the proton and deuteron targets,respectively. We calculate the $\sin2\phi$ azimuthal asymmetries in theseprocesses using the Boer-Mulders function and the longitudinal transversityfrom spectator models. We show that the study on single polarized $\pi N$Drell-Yan processes can not only give the information on the new 3-dimensionalparton distribution functions in momentum space, but also shed light on thechiral-odd structure of the longitudinally polarized nucleon.
