Technical Lecture: Stereocontrol in Photochemical Reactions<\/strong><\/h2>\n\n\n\n

Photochemistry is intriguing as a synthetic tool because the absorption of light by an organic molecule results in the formation of exceptionally energetic reactive intermediates that can react in ways that are inaccessible to ground-state molecules. However, this high reactivity is also a challenge for stereoselective synthesis: control over the stereochemistry of photochemical reactions, particularly using enantioselective catalysts, has been a long-standing challenging synthetic problem with few general solutions. We recently developed a strategy that utilizes privileged chiral Br\u00f8nsted acid scaffolds to control both the absolute and relative stereochemistry of complex [2+2] photocycloadditions. These reactions have enabled a general, concise, and stereocontrolled  strategy for the synthesis of the truxinate and truxillate natural products.<\/p>\n\n\n\n
