16. Ruthenium-catalyzed redox reactions and lipase-catalyzed asymmetric transformations of alcohols
Sammanfattning : The major part of this thesis describes the synthesis of enantiopure alcohols and diols by combining ruthenium-catalyzed redox reactions that lead to racemization or epimerization and lipase-catalyzed asymmetric trans-formations in one-pot.A mechanistic study of the unexpected facile formation of meso-diacetate products found in enzyme-catalyzed acetylations of alkanediols with Candida antarctica lipase B (CALB) was first performed.

18. Digestion and absorption of galactolipids
Sammanfattning : Galactolipids: digalactosyldiglyceride (DGalDG), monogalactosyldiglyceride (MGalDG) and sulfoquinovosyldiglyceride (SQDG) are the major lipid components in thylakoid membranes of chloroplasts i.e. the site of photosynthesis in plants. LÄS MER
19. Endocannabinoids and N-acylethanolamines in translational pain research : from monoacylglycerol lipase to muscle pain
Sammanfattning : In the early nineties cannabinoid receptors, the main target for Δ9-tetrahydrocannabinol (THC), the psychoactive component of marijuana were identified. Shortly after their endogenous ligands, N-arachidonoylethanolamine (anandamide, AEA) and 2-diacylglycerol (2-AG) were characterized. LÄS MER
20. Lipase catalysed reactions of terpenoids : formation of hemiacetal esters : resolution of cryptone and its transformation to cadinenes
Sammanfattning : During attempted enzyme-catalysed resolution of sterically hindered secondary alcohols, hemiacetals and their esters were unexpectedly detected. Hemiacetal esters are reactive compounds that decompose to alcohol, aldehyde and acid under ordinary work-up conditions i.e. in contact with water, acid, or silica gel. LÄS MER
