Claisen rearrangements in the biosynthesis of 1,1- and 1,2-dimethylallyl derivatives. The biosynthesis of the quinoline alkaloid, ravenoline
Abstract
The origin of 1,1- and 1,2-dimethylallyl residues in aryl and heterocyclic compounds is discussed, and the biosynthesis of the 1,2-dimethylallyl derivative, ravenoline, is shown to occur by rearrangement of a 3,3-dimethylallyl ether.
