Abstract
An additive-free and diastereoselective [4 + 1] annulation between ortho-hydroxyphenyl-substituted para-quinone methides and CF3-substituted imidoyl sulfoxonium ylides is developed, providing a facile and practical route to diverse trans-2,3-dihydrobenzofurans with high efficiency. This protocol features mild conditions, broad substrate scope and easy to operate.
