Phosphazene-base-catalyzed tandem addition-cyclization reaction of o-alkynylbenzaldehyde with oxygen and nitrogen nucleophiles
The tandem addition-cyclization reaction between o-alkynylbenzaldehyde and nucleophile catalyzed by P4-tBu, a phosphazene base, is demonstrated. The nucleophilic cyclization is efficiently triggered not only by alcohols, including sterically de
