摘要:
R7 is lower alkyl having 1 to 4 carbon atoms or aryl, and n is 1-4; R2 is lower alkyl having from 1 to 6 carbon atoms, cycloalkyl having 3 to 7 carbon atoms, lower alkenyl or lower alkynyl having 3 to 6 carbon atoms, or aralkyl or aryl; and R5 is lower alkenyl, lower alkynyl, or aralkyl. The R1 substitution is at the 5(6)-position. The compounds are useful as pesticides, particularly as anthelmintic and antifungal agents.
WHERE R is a lower alkyl group having 1 to 4 carbon atoms; R1 is -SOR2, -SO2R2, -SCN, -SR5, -OR5 or M'' (CH2)nMR7 where M and M'' are independently

4''-fluoro nucleosides, 4''-fluoro nucleoside analogs of Nucleocidin, 2''-deoxy-4''-fluoro pyrimidine nucleosides and novel intermediates produced in the process of preparing such compounds. The process for preparing the 4''-fluoro nucleosides of the present invention comprises treating a 4'',5''-unsaturated nucleoside with iodine monofluoride to form the corresponding 5''deoxy-4''-fluoro-5''-iodo nucleoside. The latter product is transformed to corresponding 5''-azido-5''-deoxy-4''-fluoro nucleosides, 5''-amino-5''-deoxy-4''-fluoro nucleosides,5''-deoxy-4''fluoro nucleosides, 4''-fluoro nucleosides, 5''-O-phosphoryl-4''fluoro nucleosides, and 5''-sulfamoyl-4''-fluoro nucleosides. The 2''-deoxy-4''-fluoro pyrimidine nucleosides are prepared in an analogous manner from the 4'',5''-unsaturated-2''-deoxy nucleosides. The nucleosides of this invention exhibit general antimetabolite activity and/or are intermediates for compounds exhibiting such activity.
