Article Synopsis
- * The research discusses a new method utilizing red light from LEDs and zinc tetraphenylporphyrin as a catalyst for Barton decarboxylation, avoiding dangerous reagents and excessive heating.
- * A novel one-pot reaction combining red and blue light-mediated processes demonstrates the compatibility of different photochemical methods, pushing the boundaries of traditional decarboxylative reactions.
A diaryliodonium salt-based strategy enabled the first systematic synthesis of rarely accessible -alkoxyindolines. Mechanistic analyses suggested that the reaction likely involves reductive elimination of iodobenzene from iodaoxazepine via a four-membered transition state, followed by Meisenheimer rearrangement. Substrates with -carbamate protection afforded indole in a manner similar to that of the Ishikawa indole synthesis.
