Products of Cytochrome P450BioI (CYP107H1)-Catalyzed Oxidation of Fatty Acids
摘要:
[GRAPHICS]Oxidation of tetradecanoic and hexadecanoic acids by cytochrome P450(Biol) (CYP107H1) produces mainly the 11-, 12-, and 13-hydroxy C-14 fatty acids and the 11- to 15-hydroxy C-16 fatty acids, respectively. In contrast to previous reports, terminal hydroxylation is not observed. The enantiospecificity of fatty acid hydroxylation by P450(Biol) was also determined, and the enzyme was shown to be moderately selective for production of the (R)-alcohols.
Secondary alcohols were converted into the corresponding ketones by methyl acrylate and rhodium catalyst efficiently undermicrowaveirradiation. Treatment of primary alcohols with the same condition resulted in the recovery of the starting materials. Primary alcohols were converted into aldehydes by hydrogen transfer reaction using methyl vinyl ketone and ruthenium catalyst undermicrowave irradiation
Ruthenium catalyzed isomerization of alkenol into alkanone through a migration of C–C double bond was performed in water under irradiation of microwaves. When the reaction was performed in deuterium oxide instead of water, the trail of the migration was shown by H–D exchange reaction.
