Naphtho[2,3-b]furan-4,9-dione is an important privileged structural motif which is present in natural products, drugs, and drug candidates. Herein, visible-light-mediated [3+2] cycloaddition reaction for the synthesis of naphtho[2,3-b]furan-4,9-diones and dihydronaphtho[2,3-b]furan-4,9-diones has been developed. Under environmentally friendly conditions, a variety of title compounds were delivered
萘并[2,3-b]呋喃-4,9-二酮是一种重要的特殊结构基序,存在于天然产物、药物和候选药物中。在此,用于合成萘并[2,3-b]呋喃-4,9-二酮和二氢萘并[2,3-b]呋喃-4,9-二酮的可见光介导的[3+2]环加成反应具有已开发。在环境友好的条件下,多种标题化合物均以良好的收率得到。这种新方案显示出优异的区域选择性和显着的官能团耐受性。该方法提供了一种强大、绿色、高效且简便的方法来扩大萘并[2,3-b]呋喃-4,9-二酮和二氢萘并[2,3-b]呋喃-4,9的结构多样性-二酮作为新药发现的有前途的支架。
