Reaction of (dimethylvinylidene)carbene with indole-3-carbaldehyde and its application in the synthesis of β-(dehydroprenyl)indole-based natural products
Abstract
Reaction of (dimethylvinylidene)carbene with indole-3-carbaldehyde gives various dehydroprenyl-based indoles. Efficient synthesis of the indole natural products yuehchukene and murrapanine, using this reaction as a key step, is also described.
