A formal synthesis of valiolamine from myo-inositol

, p. 7963 - 7970 (2011/11/14)
An efficient formal synthesis of racemic valiolamine starting from readily available myo-inositol is reported. In all the synthetic steps only one regioisomer is formed, which circumvents laborious purification of products. Regioselective benzylation of myo-inositol orthoformate, super-hydride mediated deoxygenation of a cyclitol derivative and stereoselective addition of dichloromethyllithium to an inosose are the key reactions in the synthesis.

The synthesis of a novel carbasugar amino acid (15), starting from D-glucose and using the Ferrier rearrangement as a key step, is reported. Compound 15 is implemented as dipeptide isostere in the synthesis of a Leu-enkephalin analog. Copyright Taylor & F
Biological activities of α-mangostin derivatives against acidic sphingomyelinase

Deprenyl and benzofenone-type congeners of α-mangostin 1 have been synthesized to understand their role for the inhibitory activity against sphingomyelinase (SMase). While removal of the prenyl group of the right side (11 and 12) caused loss of the selectivity between ASMase (acidic sphingomyelinase) and NSMase (neutral sphingomyelinase), the prenyl group of the left side appeared to increase the inhibitory activities (16 and 17).
The first direct synthesis of α-mangostin, a potent inhibitor of the acidic sphingomyelinase

, p. 291 - 293 (2007/10/03)
A total synthesis of α-mangostin 1a has been achieved. The key cyclization reaction to construct the xanthone framework was undertaken by employing the PPh3-CCl4 conditions. The inhibitory activities of 1a and the benzophenone intermediate 16 against the acidic sphingomyelinase were discussed.
