Abstract
AbstractIn the presence of iodine, the synthesis of S‐benzoazolyl chromone derivatives by one‐pot manner is reported. Thus, 2‐aminophenol firstly reacted with tetramethylthiuram disulfide (TMTD) to form 2‐mercaptobenzoxazole, and then coupled with 2‐hydroxyphenyl enaminones to obtain S‐benzoazolyl chromones through one‐pot manner. This method features mild conditions, easy operation, environmentally friendliness and wide substrate scopes, illustrating practical application value in organic synthesis.
