1-(tert-butylsulfinyl)isoquinoline 2 with the 1-naphthyl Grignardreagent 4. Resolution of the ligand 6 was achieved through chromatographic separation of the Noe-lactol® derivatives. The absolute configuration of (R)-(-)-6 was determined by a single crystal X-ray study of the p-bromobenzoate derivative 9. (R)-(-)-6 enantioselecdvely catalysed the addition of diethylzinc to benzaldehyde, affording (S)-(-)
