I'm trying this to use \Bigl( and \Bigr), but even a simple equation as this one is not working
\begin{align*}
\Bigl( a b \Bigr)
\end{align*}
any solutions would be grateful

Environment align* is defined by package amsmath:
\documentclass{article}
\usepackage{amsmath}
\begin{document}
\begin{align*}
\Bigl( a b \Bigr)
\end{align*}
\end{document}
This code works fine.
