    摘要: The present invention relates to α-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 α-amino acid phenyl ester derivatives as hypnotics for the induction and maintenance of general anaesthesia.
