The methoxymethyl (MOM) group gains recently importance as a hydroxyl-pro- tecting group!. It has been successfully employed in many syntheses also in our LaboratoryZ - II. Since rapid identification of this group was needed during the synthetic work, we developed a detection method based on the infrared spectroscopy. We have extended the series of the already prepared and measured compounds by known12 (VI, VII and XIII), as well as neW (I, II, V, XII, XlV, ...
