  • Synthesis of acyclic nucleoside derivatives
    Patent number: 6184376
    Abstract: Methods and novel intermediates of the formula: wherein R6 and R7 are lower alkyl or benzyl or R6 and R7 taken together are —CH2CH2—, —CH2CH2CH2— or —CH2CH2CH2CH2CH2—, R8 is C1-C21 alkyl or a C2-C21 monounsaturated alkenyl, which may optionally be substituted with substitution substituents independently selected from the group consisting of hydroxy, C1-C6 alkyl, C1-C6 alkoxy, C1-C6 alkoxy C1-C6 alkyl, C1-C6 alkanoyl, amino, halo, cyano, azido, oxo, mercapto and nitro, and R9 is an alcohol protecting group. The intermediates are useful for the preparation of acyclic nucleoside derivatives of the formula: where one of R1 and R2 is an amino acid acyl group and the other of R1 and R2 is a —C(O)C3-C21 saturated or monounsaturated, optionally substituted alkyl and R3 is OH or H; or a pharmaceutically acceptable salt thereof.
