Converting a Newman projection to a Fischer projection. First convert the staggeredconformer of the Newman projection to an eclipsed conformer by rotating either the frontor back carbon. (Here the carbon in front is not moved while the back carbon is rotatedcounterclockwise.) Now you can draw the Fischer projection by pulling down the bondattached to the CH3 group on the back carbon. As a result, the front carbon in the Newmanprojection becomes the top cross in the Fischer projection and the back carbon becomes thebottom cross. Notice that the bond to the CH3 group on the back carbon, which points tothe top of the page in the eclipsed Newman projection, now points to the bottom of the pagein the Fischer projection. Next, add the other atoms to their bonds, keeping the atoms on theright side of the Newman projection on the right side of the Fischer projection and the atomson the left side of the Newman projection on the left side.
