A procedure is described for the in situ generation of functional equivalents of glutaric, succinic, and malonic dialdehydes. DIBAL-H reduction of the corresponding 1,n-dioates followed by in situ addition of a nucleophilic trapping agent allows for one-pot, bidirectional homologation. Olefination and Grignard addition classes of reactions are specifically demonstrated.
本文描述了一种原位生成戊二醛、琥珀醛和苹果酸二醛功能相似物的程序。通过DIBAL-H还原相应的1,n-二酰酸,并随后原位添加亲核捕获试剂,实现了一锅法的双向同源化。特别演示了烯化和格氏试剂加成反应类别。
