Code to create a redirection after login?

You can use the login_redirect hook.

function redirect_admin( $redirect_to, $request, $user ){

    //is there a user to check?

    if ( isset( $user->roles ) && is_array( $user->roles ) ) {

        //check for admins
        if ( in_array( 'administrator', $user->roles ) ) {

            $redirect_to = WP_HOME.'/quote-list/'; // Your redirect URL
        }
    }

    return $redirect_to;
}

add_filter( 'login_redirect', 'redirect_admin', 10, 3 );

Example taken from WordPress Codex

Also is_admin() does not check if the user is an administrator but if the administration panel is being displayed.
