Egon Spengler cluelessness on what the word "epididymis" was. Egon primarily worked with Ray, both of whom were still living at the Firehouse, conducting research on the pink slime. Still very scientifically minded, Egon seems to have loosened up a little bit, letting his sense of humor show and even giving Dana a smile and Peter (who was carried away with photographing Vigo's portrait), a knowing smile. Although the 2016 "Ghostbusters" film is a reboot, the film's marketing confirms that a version of Egon Spengler does exist in the film's fictional universe. According to a tie-in video to the film, Kate McKinnon's
Pictet–Spengler reaction amination. The benzyl group can be removed hydrogenolytically afterwards. As a rough rule, C NMR signals for C1 and C3 are downfield shifted in "cis" products relative to "trans" products (see steric compression effect). Pictet–Spengler reaction The Pictet–Spengler reaction is a chemical reaction in which a β-arylethylamine undergoes condensation with an aldehyde or ketone followed by ring closure. The reaction was first discovered in 1911 by Amé Pictet and Theodor Spengler. Traditionally an acidic catalyst in protic solvent was employed with heating, however the reaction has been shown to work in aprotic media without acid catalysis in superior yields for
