How to draw newman projections from wedge dash.
A Fischer projection is always in the eclipsed conformation. To draw the sawhorse projection of an eclipsed conformation, start out by first drawing a line representing the carbon-carbon bond sloping upward and to the right (Pause the video as you trace these steps). Then draw one bond in front and one in back exactly straight down. Next, add ...
Consider the dash-weage drawing shown below and consider the possible Newman projections shown below the dash-wedge drawing from the perspective of the eye shown.

Fischer projections are just another way of drawing compounds contacting chirality centers. They were initially proposed by Emil Fischer for making it easier to draw the structures of compounds containing multiple chirality centers with the main idea of not having to draw the wedge and dash lines for every single chiral center. Sawhorse Projection to Fischer Projection. First, the staggered Sawhorse projection is converted to an eclipsed projection. It is then held in the vertical plane in such a manner that the two groups pointing upwards are away from the viewer, i.e. both these groups are shown on the vertical line. Such a conversion for 2,3-dibromobutane is shown.#wedge_dash_to_fisherwedge dash to fisher projection stereochemistry detailed lecture.This video is all about #conversion #trick #from #wedge #dash #to #fish...
