We start by creating the base skeleton using cyclo-430-nonane, followed by adding pi bonds and substituting specific carbon atoms with nitrogen heteroatoms. I demonstrate how to add a double-bonded oxygen to complete the structure. Feel free to interact with the final molecule by dragging it around or zooming in and out. I encourage you to follow along and practice these steps to enhance your understanding of heteroatom molecule design.</description></oembed>
