title: Synthesis of 4'-C-ethynyl-beta-D-arabino- and 4'-C-ethynyl-2'-deoxy-beta- D-ribo-pentofuranosyl pyrimidines, and their biological evaluation.
abstract: 4'-C-Ethynyl-beta-D-arabino-pentofuranosyl thymine (14) and cytosine (16), and 4'-C-ethynyl-2'-deoxy-beta-D-ribo-pentofuranosyl thymine (25) and cytosine (27) were synthesized by properly protected 4'-C-hydroxy-methyl-3,5-di-O-benzyl-alpha-D-ribo-pentofuranose (1) from D-glucose. Among them, 2'-deoxy derivatives 25 and 27 exhibited antiviral activity, while cytidine derivatives 16 and 27 inhibited the growth of neoplastic cells.
