Paragraph 0265; 0266, (2016/09/26)
An object of the present invention is to provide a compound represented by formula (I) which is highly specific to tau and can image tau with satisfactory sensitivity, and also has high brain transition, low or non-recognized bone-seeking properties and low or undetected toxicity.
A pre-RNA candidate revisited: Both enantiomers of flexible nucleoside triphosphates are DNA polymerase substrates
Heuberger, Benjamin D.,Switzer, Christopher
, p. 412 - 413 (2008/09/19)
One of the earliest proposed pre-RNA candidates is the flexible nucleic acid (FNA) structure based on the mixed acetal aminal of formyl glycerol. FNA achieves dramatic stereochemical simplification by formally deleting the 2′-CHOH group of RNA, thereby re

, p. 367 - 370 (2008/04/01)
An easy preparation of optically active 1,2-diol monotosylate derivatives by enzymatic hydrolysis is disclosed. Lipase PS (Burkholderia cepacia) catalyzes the hydrolysis of racemic 2-acetoxyhexyl tosylate with excellent enantioselectivity to afford the corresponding optically active compounds. In this reaction, a unique temperature effect is observed. After optimizing the reaction conditions, this procedure is widely applicable to the practical preparation of both enantiomers of various optically active compounds with high ee.

scheme or table, p. 2981 - 2984 (2009/10/17)
Lipase PS catalyzes the enantioselective hydrolysis of various 2-acetyl compounds of the 1-O-alkyl-3-O-arylsulfonyl-sn-glycerol derivatives to afford the corresponding optically active compounds. Changing the structure of the 1-O-alkyl and 3-O-arylsulfonyl groups affects both the reactivity and enantioselectivity. Finally, the E value of the reaction for 2-acetyl-3-O-3,5-dimethylbenzenesulfonyl-1-O-4-methoxybenzyl-sn-glycerol is greater than 200. Georg Thieme Verlag Stuttgart.

, (2008/06/13)
This invention relates to a novel solution phase process for the preparation of tertiary amine combinatorial libraries. These libraries have utility for drug discovery and are used to form wellplate components of novel assay kits.
Stereoselective total synthesis of (2R,2′S,3Z)-1-O-(2-methoxyhexadecenyl) glycerol and (2R,2′S)-1-(2′-methoxyhexadecyl)glycerol-potential antitumour compounds from Shark liver oil
Baig, Mirza Hamed A.,Baskaran, Subramanian,Banerjee, Sharmila,Trivedi, Girish K.
, p. 4723 - 4732 (2007/10/02)
A simple and high yielding route for the stereoselective synthesis of alkyl glycerol ethers namely (2R,2′S,3Z)-1-O-(2-methoxyhexadecenyl)glycerol 1 and (2R,2′S)-1-(2′-methoxyhexadecyl) glycerol 2, isolated form Shark liver oil is reported. The key reaction involves the Wittig olefination of the chiral aldehyde 12 with the ylide generated from tridecyl triphenyl phosphonium bromide results in the formation of compound 13, a precursor for the title compounds 1 and 2.
SYNTHESIS OF(2R) AND (2S)-BENZYL-2,3-EPOXYPROPYL ETHER FROM A COMMON PRECURSOR: O-BENZYL-L-SERINE
Witt, P. De,Misiti, D.,Zappia, G.
, p. 5505 - 5506 (2007/10/02)
The (2R) and (2S)-benzyl-epoxypropyl ether are obtained from commercially available O-benzyl-serine, via nitrosation and Mitsunobu reactions to afford the chiral precursors of the above epoxy ethers.

Byun, Hoe-Sup,Bittman, Robert
, p. 2751 - 2754 (2007/10/02)
Ring opening of (R)- and (S)-glycidyl tosylates with benzyl alcohol, followed by treatment with K2CO3/MeOH gave (S)-(+)- and (R)-(-)-benzylglycidyl ether in 90percent overall yield.
