Nonracemic beta -blockers, viz., (S)-propranolol and (S)-timolol, were prepared from (S)-glycidol in three steps consisting in the reaction with SOCl2 followed by the reaction of the resulting (4S)-4-chloromethyl-2-oxo-1,3,2-dioxathiolanes with the corresponding phenol and the final cleavage of (4R)-aryloxymethyl sulfites under the action of amines in DMF.

approaches, our architecture is fully distributed and includes agents who preserve the privacy and autonomy of their users. These agents learn models of each other in terms of expertise (ability to produce correct domain answers) and sociability (ability to produce accurate referrals). We study our framework experimentally to study how the social network evolves. Specifically, we find that under our multi-agent

The present invention relates to compounds of formula (I), or pharmaceutically acceptable salts, solvates thereof, that bind to Inhibitor of Apoptosis Proteins (IAPs). The compounds of the invention may be used as diagnostic and therapeutic agents in the treatment of proliferative diseases, such as cancer, for promoting apoptosis in proliferating cells, and for sensitizing cells to inducers of apoptosis. The present invention furthermore provides a polymeric compound of formulas (VI) or (VII), comprising either at least two monomeric units of compounds of formula (I), or at least one monomeric unit of a compound of formula (I) and an entity E. The present invention further relates to pharmaceutical compositions comprising said compounds of formulas (I), (VI), and (VII) and the use of said compounds in medicine.

ethers du titre subissent une scission de la liaison H 2 C-O lorsqu'ils sont traites par les radicaux anioniques de l'anthracene ou du fluoranthrene. Dans des conditions comparables les naphtylmethyl phenyl ethers reagissent plus de 10 4 fois plus vite que les naphtylbenzyl ethers. Interpretation
Les ethers du titre subissent une scission de la liaison H 2 CO lorsqu'ils sont traites par les radicaux anioniques de l'anthracene ou du fluoranthrene。Dans des conditions 可比 les naphtylmethyl phenyl ethers reagisent plus de 10 4 fois plus vite que lesnaphtylbenzyl ethers。解释
