in the highly diastereoselective synthesis of more than 20 different anti-amino alcohols (63–90% yields with up to 20 : 1 dr). Cleavage of the pyrrolo-N-protecting group was accomplished, e.g. in the presence of NH2OH under microwave conditions with yields exceeding 80%. The applicability of the protecting groups was further demonstrated by a short total synthesis of the sphinganine-like natural product
