The present invention relates to &agr;-amino acid phenyl ester derivatives having general formula (I) wherein R1 is (C1-3)alkyloxy; R2 is (C1-3)alkyl, (C1-3)alkyloxy or (C2-3)alkenyl; R3 is hydrogen, (C1-3)alkyl, (C1-3)alkyloxy or (C2-3)alkenyl; R4 is (C1-6)alkyl; R5 and R6 are independently (C1-6)alkyl, (C2-6)alkenyl, (C2-6)alkynyl or aralkyl, each of which may be optionally substituted with (C1-3)alkyloxy, (C1-3)alkyloxycarbonyl, cyano or NR7R8; R7 and R8 are independently (C1-6)alkyl; or a pharmaceutically acceptable salt thereof. The invention also relates to pharmaceutical compositions comprising said derivatives, and to the use of these &agr;-amino acid phenyl ester derivatives as hypnotics for the induction and maintenance of general anaesthesia.

In the search for a novel water-soluble general anesthetic agent the activity of an alpha-amino acid phenolic ester lead, identified from patent literature, was markedly improved. In addition to improving in vivo activity in mice, good in vitro activity at GABA(A) receptors was also conferred. Within the series of compounds good enantioselectivity for both in vitro and in vivo activity was found, supporting
