摘要
A convenient synthesis of cis-(+/-) isomer 1 and trans-(+/-) isomer 2 of lamivudine starting from benzoyloxyacetaldehyde and 1,4-dithiane-2,5-diol is described. The key steps include chlorination of oxathiolane lactol 5 by SOCl2/DMF, followed by coupling with silylated N-4-acetylcytosine and deprotection. The overall yield was 42.6% and 20.1%, respectively.
