traceless isoprenylation of aldehydes via n boc n 1 1 dimethylallyl hydrazones
European Journal of Organic Chemistry, 2020Co-Authors: Desirée Heerdegen, Julia Junker, Sebastian Dittrich, Peter Mayer, Franz BracherAbstract:A short isoprenylation protocol starting from non‐conjugated N‐Boc‐N‐(1,1‐dimethylallyl)hydrazones was developed utilising Thomson's traceless bond construction. This type of [3,3]‐sigmatropic rearrangement is catalysed by the Bronsted acid triflimide and liberates only gaseous by‐products. The required N‐Boc‐N‐allylhydrazine precursor is available in three steps starting from a known diazene using biocatalytic aldol addition and Tebbe Olefination as key steps. Allylhydrazones are prepared via condensation with appropriate aldehydes. Scope and limitations of the [3,3]‐sigmatropic rearrangements are analysed.
