Cascade Resulting in the Reductive Ethynylation of Aldehydes: Dissection of Its Components
摘要:
A mild and efficient two-carbon homologation of aldehydes exploiting multiple modes of KOt-Bu was developed. This process involves a sequential Peterson allenylation/allene-alkyne isomerization/protodesilylation in a single-flask operation. The differential roles played by the various elements of the process were demonstrated through dissection experiments.
