The biosynthesis of vitamin D₂ is a two-step reaction, requiring two types of concerted pericyclic reactions. Draw in the arrows for each step and identify the structure of precalciferol. If an electrocyclic reaction is required, identify if it occurs through a conrotatory or disrotatory reaction. HO H H ergosterol hv precalciferol HO H ergocalciferol
