Al~tract: A pyrimidine moiety was tethered at the 3'-~-position of D-threo-furanosides. By carefully controlling the reaction conditions, pyrimidine bases can be delivered to the anomeric center to give of ~-pyrimidine nucleosides in good yield and with complete stereocontrol.
Stereocontrolled Synthesis of β-2'-Deoxypyrimidine Nucleosides via Intramolecular Glycosylations. -In continuation of efforts to develop general methods for the exclusive formation of β-nucleosides, the base-promoted reaction of the pentafuranoside (II) with allyloxypyrimidines (II) is reported. Af
## Abstract The photochemical reactions of different __N__‐(2‐acylphenyl)‐2‐bromo‐2‐methylpropanamides have been investigated. Irradiation of the __N__‐unsubstituted anilides **1a**–**1c** gave the corresponding dehydrobromination, cyclization, and bromo‐migration products **2, 3**, and **4**, resp
