英文摘要	An efficient [4+1] cycloaddition of ortho-hydroxyphenylsubstituted para-quinone methides, and sulfur ylides was achieved under the catalyst-free condition. With this developed protocol, a series of trans-2,3-dihydrobenzofurans were obtained in excellent yields (up to 99%) with high diastereoselectivities (>20:1 dr). The usefulness of the protocol was also demonstrated by the versatile conversions of the 2,3-dihydrobenzofurans into other functionalized benzofurans. (C) 2017 Elsevier Ltd. All rights reserved.
