Preheat oven to 350°F Place butter in 9-inch round cake pan; place pan in oven while preheating to melt butter.
Meanwhile, unroll dough on cutting board. Combine sugar and cinnamon in small bowl; sprinkle over dough. Sprinkle with chocolate chips. Starting with short side, roll up dough jelly-roll style. Cut into 8 slices with serrated knife.
Remove pan from oven. Stir pecans and maple syrup into melted butter. Arrange slices cut side down in pan, pressing gently into nut mixture.
Bake 20 minutes or until golden brown. Immediately invert pan onto serving plate, scraping any nuts and butter mixture onto buns. Serve warm.
