Chandra, Girish,Moon, Yang Won,Lee, Yoonji,Jang, Ji Yong,Song, Jayoung,Nayak, Akshata,Oh, Kawon,Mulamoottil, Varughese A.,Sahu, Pramod K.,Kim, Gyudong,Chang, Tong-Shin,Noh, Minsoo,Lee, Sang Kook,Choi, Sun,Jeong, Lak Shin

On the basis of the potent inhibitory activity of neplanocin A (1) against S-adenosylhomocysteine (AdoHcy) hydrolase, we analyzed the comprehensive structure-activity relationships by modifying the adenine and carbasugar moiety of 1 to find the pharmacoph
Synthesis of (-)-neplanocin A with the highest overall yield via an efficient Mitsunobu coupling
Michel, Beno?t Y.,Strazewski, Peter
, p. 9836 - 9841 (2008/02/11)
Neplanocin A was synthesized in very high isolated yield and purity, in 10 steps from d-ribose via an efficient Mitsunobu coupling using N6-bis-Boc-protected adenine. In fact, this synthesis is a short pathway to enantiopure neplanocin A giving

An improved approach to enantiomerically pure hydroxylated cyclopentenones is reported here, which involves intramolecular nitrone cycloaddition of sugar-derived chiral pent-4-enals and hex-5-en-ones-2 followed by N-O bond cleavage, quaternization of the amine thus produced, and finally oxidative elimination of the amino group. Synthesis of pentenomycin I and neplanocin A is described following this methodology.
Enantiomeric synthesis of D- and L-cyclopentenyl nucleosides and their antiviral activity against HIV and West Nile virus
Song,Paul,Choo,Morrey,Sidwell,Schinazi,Chu
, p. 3985 - 3993 (2007/10/03)
Enantiomeric synthesis of D- and L-cyclopentenyl nucleosides and their antiviral activity against HIV and West Nile virus are described. The key intermediate (-)- and (+)-cyclopentenyl alcohols (7 and 15) were prepared from D-γ-ribonolactone and D-ribose,
Palladium-catalyzed enantioselective synthesis of carbanucleosides
Trost, Barry M.,Madsen, Robert,Guile, Simon D.,Brown, Brian
, p. 5947 - 5956 (2007/10/03)
A general strategy has been developed for enantioselective synthesis of diverse carbanucleosides. The key step is a Pd(0)-catalyzed enantioselective allylic amination of cis-3,5-dibenzoyloxycyclopent-2-ene 10a with the nucleobase. With guanine-derived nuc
A concise synthesis of (-)-neplanocin A

, p. 4677 - 4678 (2007/10/03)
A concise stereocontrolled route to (-)-neplanocin A, a naturally occurring carbocyclic nuleoside, has been developed by employing lipase- mediated kinetic resolution.
An enantio- and diastereo-controlled synthesis of (-)neplanocin A and its 2,3-di-epi isomer
Trost, Barry M.,Madsen, Robert,Guile, Simon D.
, p. 1707 - 1710 (2007/10/03)
An enantioselective Pd catalyzed desymmetrization of cis-3,5-dibenzoyloxycyclopent-2-ene combined with a diastereoselective epoxidation provided a common intermediate that can bifurcate to form either (-)-neplanocin A or its 2,3-di-epi isomer.
Synthesis of (-)-Neplanocin A via C-H Insertion of Alkylidenecarbene
Ohira, Susumu,Sawamoto, Tsukasa,Yamato, Masatoshi
, p. 1537 - 1538 (2007/10/02)
(-)-Neplanocin A, a naturally occurring carbocyclic nucleoside was synthesized via C-H insertion reaction of the alkylidenecarbene, which was generated by the reaction of lithiotrimethylsilyldiazomethane and the ketone derived from D-ribose.
3′-deoxy-3′-fluoro-xyloneplanocin A
Borthwick, Alan D.,Biggadike, Keith
, p. 3237 - 3240 (2007/10/02)
Neplanocin A has been efficiently converted in three steps into its 3′-deoxy-3′-fluoro-xylo-analogue.
Enantiospecific Syntheses of Aristeromycin and Neplanocin A
Wolfe, Michael S.,Anderson, Blake L.,Borcherding, David R.,Borchardt, Ronald T.
, p. 4712 - 4717 (2007/10/02)
The carbocylic nucleosides (-)-aristeromycin and (-)-neplanocin A were made enantiospecifically in nine steps and ten steps, respectively, from D-ribonic acid γ-lactone.Quenching of an organocuprate conjugate addition reaction with either acetic acid or methanesulfinyl chloride determines whether the divergent synthetic route branches toward (-)-aristeromycin or (-)-neplanocin A.An alternate synthesis of cyclopentenone 1, a common intermediate to these compounds, from D-gulonic acid γ-lactone is also described.
