Asymmetric synthesis of iridoid derivatives using resolved 2-phenylindoline as a chiral auxiliary

10.1002/ejoc.200800440

The research focuses on the asymmetric synthesis of iridoid derivatives, specifically cis,cis-nepetalactol, using resolved 2-phenylindoline as a chiral auxiliary. The study involves the cycloaddition of oxocitral with 2-phenylindoline, which was resolved into enantiomers through chromatographic separation of diastereomers formed with (R)-(+)-α-methylbenzyl isocyanate. The experiments included NMR spectroscopy for product characterization, computational methods for conformational analysis, and various synthetic procedures to prepare the reactants, such as the reduction of 2-phenylindole to 2-phenylindoline. The enantiomeric purity of the resolved products was analyzed using chiral gas chromatography, confirming the success of the asymmetric synthesis route.
