Draw the Newman projection so that it corresponds to the molecule and conformation shown when viewed down the red bond in the direction of the red arrow. Your projection should be oriented as shown by the arrow marked up. So the CH₂SH group on the front carbon should be above the H and H₂C groups, no matter which template you use. Lax HS up H SH
