Unroll crescent rolls, and separate each can into 2 rectangles, pressing perforations to seal. Brush evenly with 2 tablespoons melted butter.
Stir together chopped pecans and next 3 ingredients; sprinkle 3 tablespoons pecan mixture onto each rectangle, pressing in gently.
Roll up, starting at one long side, and twist. Cut 6 shallow 1/2-inch-long diagonal slits in each roll.
Shape rolls into rings, pressing ends together; place on a lightly greased baking sheet. Brush rings evenly with remaining 1 tablespoon butter.
Bake at 375° for 12 minutes or until rings are golden.
Stir together powdered sugar and maple syrup until glaze is smooth; drizzle over warm rings. Cut rings in half, and serve.
