Compound 8 which could be used as a versatile precursor for the synthesis of 5,7-membered fused ring containing natural products was synthesized via tandem Pummerer rearrangement and intramolecular [4+3] cycloaddition in moderate yield and with high diastereoselectivity.
通过串联Pummerer重排和分子内[4 + 3]环加成反应,以中等收率和高非对映选择性合成了可用作合成5,7元稠环天然产物的通用前体的化合物8。
