摘要:Disclosed is a process for the synthesis of (3R)-3-hydroxy-β-ionone and its (3S)-enantiomer in high optical purity from commercially available (rac)-α-ionone. The key intermediate for the synthesis of these hydroxyionones is 3-keto-α-ionone ketal that was prepared from (rac)-α-ionone after protection of this ketone as a 1,3-dioxolane. Reduction of 3-keto-α-ionone ketal followed by deprotection, lead to 3-hydroxy-α-ionone that was transformed into (rac)-3-hydrox-β-ionone by base-catalyzed double bond isomerization in 46% overall yield from (rac)-α-ionone. The racemic mixture of these hydroxyionones was then resolved by enzyme-mediated acylation in 96% ee. (3R)-3-Hydroxy-β-ionone and its (3S)-enantiomer were respectively transformed to (3R)-3-hydroxy-(β-ionylideneethyl)triphenylphosphonium chloride [(3R)-C 15 -Wittig salt] and its (3S)-enantiomer [(3S)-C 15 -Wittig salt] according to known procedures. Double Wittig condensation of these Wittig salts with commercial available 2,5- dimethtylocta-2,4,6-triene-1,8-dial provided all 3 stereoisomers of zeaxanthin. Similarly, (3R)-C 15 -Wittig and its (3S)-enantiomer were each coupled with β-apo-12′-carotenal.

摘要:This invention relates to the synthesis of dithiocarboxylic acid esters by reaction of bis(thioacyl) disulphides, thioacetals or vinylidane bis(thioether) with free-radicals (optionally in the presence of monomers). The invention also relates to processes for the synthesis of polymers utilising these dithioesters as polymerisation regulators (chain transfer agents) or to the use of bis(thioacyl) disulphides to generate dithioester chain transfer agents in situ.

权利人:NITTO DENKO CORP
摘要:According to the invention, there is provided a solid-phase support for nucleic acid synthesis, which is constituted of a porous copolymer particle containing a multifunctional vinyl monomer unit having two or more vinyl groups in one molecule and a monofunctional vinyl monomer unit having one vinyl group in one molecule, in which the solid-phase support has a swelling volume when soaked in acetonitrile of 3.5 ml/g or more and has a median particle diameter measured by a laser scattering particle size distribution measuring method within a range of from 50 to 120 µm. According to the solid-phase support for nucleic acid synthesis of the invention, a high-purity nucleic acid can be synthesized with a high yield.
