γ-Functionalised β-methylene organolithium compounds from 3-chloro-2-(chloromethyl)propene: Synthetic applications
摘要:
The reaction of functionalised methallylic chlorides 1 with an excess of lithium powder and a catalytic amount of naphthalene (8 mol %) in the presence of a carbonyl compound (Barbier-type conditions) at -78-degrees-C leads, after hydrolysis with water, to the corresponding polyfunctionalised compounds 2. Starting materials 1 are easily available from 3-chloro-2-(chloromethyl)propene by nucleophilic substitution.
