[3+2]‐cycloaddition of ortho‐diazoquinones with enol ethers has been developed to provide fused polycyclic 2,3‐dihydrobenzofurans, including diversity‐oriented total synthesis of aflatoxin B2. Additionally, the utility of this method was demonstrated to other aflatoxin family members and the central core skeleton of rocaglamide natural product.
                                    已开发了Rh催化的邻重氮醌与烯醇醚的[3 + 2]环加成反应,以提供稠合的多环
2,3-二氢苯并呋喃,包括以多样性为导向的
黄曲霉毒素B 2的全合成。此外,该方法的效用已证明对其他
