We consider N=1 F-theory and Type IIB orientifold compactifications derive new \alpha' corrections to the four-dimensional effective action. They originate from higher derivative eleven-dimensional supergravity survive M-theory limit. find a correction Kahler moduli depending on non-trivial intersection curve of seven-branes. also analyze curvature correction.
