role in its antiepileptic properties. Using this novel molecular target, we initiated a drug-discovery program searching for ligands with significant affinity to LBS with the aim to characterize their therapeutic potential in epilepsy and other central nervous system diseases. We systematically investigated the various positions of the pyrrolidone acetamide scaffold. We found that (i) the carboxamide moiety

The invention provides a compound of Formula I: or a pharmaceutically acceptable salt thereof as described herein. The invention also provides pharmaceutical compositions comprising a compound of Formula I, processes for preparing compounds of Formula I, the compound of formula (I) for use in therapeutic methods for treating the proliferation of the HIV virus, treating AIDS or delaying the onset of AIDS symptoms in a mammal using compounds of Formula I. Preferred compounds are N-[(2S) -1-[2-[(2S,3S)-2-hydroxy-3-[[(2S)-2-(methoxycarbonylamino) -3,3-dimethylbutanoyl]amino]-4-phenylbutyl]-2-[(phenyl) methyl]hydrazinyl]-3,3-dimethyl-1-oxobutan-2-yl]carbamate atazanavir (ATV) analogues substituted by several heterocycles, such as e.g. pyrazole (Rl); e.g. oxetane (substituent of X2); e.g. pyridine or pyrimidine (X1); e.g. piperazine or 3,8-diazabicyclo[3.2.1]octan (X2).

Disclosed is a process for making diastereomeric N-sulfinyl α-amino amides by reaction of chiral sulfinimines with formamides and lithium diisopropylamide. The process of the invention provides the N-sulfinyl α-amino amides in high yields and with high diastereoselectivity.
Henry reaction of various aldehydes with nitromethane. It was found that these compounds were effective catalysts for this reaction, with enantiomeric excesses being as high as 97%. The enantioselectivities of individual derivatives were different and depended on the substituents attached to stereogenic centers and the configuration of imidazolidine-4-one cycle. High enantiomeric excesses were obtained

[reaction: see text]. Diastereoselective Strecker reactions based on (R)-phenylglycine amide as chiralauxiliary are reported. The Strecker reaction is accompanied by an in situ crystallization-induced asymmetric transformation, whereby one diastereomer selectively precipitates and can be isolated in 76-93% yield and dr > 99/1. The diastereomerically pure alpha-amino nitrile obtained from pivaldehyde
