Resumen de Push, Pivot, and Pull Your Way to Converting Fischer Projections into Staggered Bond-Line Structures
Interconverting different molecular representations can be problematic for many organic chemistry students. This is certainly the case when converting Fischer projections into bond-line structures. When performing the conversion from a Fischer projection into an all-staggered bond-line structure, students are sometimes taught to draw the fully eclipsed conformer first; for smaller molecules, the conversion to a fully eclipsed bond-line representation is relatively straightforward, while the conversion into the staggered conformation is not always as trivial. A systematic approach using the mnemonic “push–pivot–pull” described herein provides organic chemistry students with another option for producing a staggered bond-line structure from the corresponding Fischer projection while foregoing the fully eclipsed representation altogether.
