Natural (−)-geosmin 11, (+)-octalone 14 (from Vetiveria zizanioides), and (+)-octalin 15 (from Bazzania fauriana and B. angustifolia) have been prepared in high chemical and enantiomeric yields via the asymmetric process involving Michael-type alkylation of chiral imines 6 and 12. Enant-(+)-geosmin has been also synthesized by the same procedure.
High pressure-mediated Michael addition of chiral imines derivedfrom 2-methylcyclopentanone, 2-methylcyclohexanone and opticallyactive 1-phenylethylamine, to methyl and phenyl crotonates was investigated. The corresponding adducts were obtained in fair yields and with a high degree of regio-, diastereo- and enantioselectivity.

A compound of Formula (I) is provided that has been shown to be useful for treating a disease, disorder or syndrome that is mediated by the transportation of essential molecules in the mmpL3 pathway: (I) wherein R1, R2, R3, R4, R5 and R6 are as defined herein.
chiral imines 2, 9 and the acrylate 3. Reduction of the carbonyl group of the resulting adducts 4 and 10 with KBH 4 followed by lactonization and HWE reaction with formaldehyde yielded the lactones 7 and 13 as mixtures of diastereoisomers. Diastereoselectivity in the reduction of chiral 5-oxoalkanoic acids 4 and 10 was improved by combination of metal salt and hydride reducing agent.
