The present invention provides compounds and pharmaceutical compositions for inhibiting N-acylethanolamine acid amidase (NAAA). Inhibition of NAAA is contemplated as a method to sustain the levels of palmitoylethanolamide (PEA) and oleylethanolamide (OEA), two substrates of NAAA, in conditions characterized by reduced concentrations of PEA and OEA. The invention also provides methods for treating inflammatory diseases and pain, and other disorders in which decreased levels of PEA and OEA are associated with the disorder.

syn-(S)-beta -Hydroxy-alpha -amino acids were synthesised stereoselectivity via elaboration of the asymmetric aldol reactions of aldehydes with a chiral Ni(II)-(S)-BPB/glycine Schiff base comp]es in the presence of equimolar NaH in THF. The stereoselectivity of the reaction was studied as a function of rime. the reaction conditions. the nature of the carbonyl compounds and the base used. The synthetic potential of this asymmetric method was demonstrated in the preparation of syn-(S)-beta -hydroxyleucine on a multi-gram scale. (C) 2001 Elsevier Science Ltd. All rights reserved.
