Draw the major organic products obtained from the reactions below. Be mindful of stereochemistry and regioselectivity. If stereochemistry is included in the product, note that the diast/enant is also included, but not provided due to space. Assume one equivalent unless stated otherwise, or if the reagent is a solvent, oxidant or reductant.
