In this article we investigate the structure of four-point functions AdS3-WZNW model. We consider integral expression for unflowed correlator involving at least one state in discrete part spectrum derived by analytic continuation from H 3 + -WZNW model and show that conformal blocks can be obtained those with an extremal-weight means intertwining operator. adapt procedure dealing correlators a single unit spectral flow charge get factorized corresponding function. finally transform formulas back to space-time picture.
