## Abstract Intramolecular condensation of the __N__โ(4โaminoโ5โnitrosopyrimidinโ4โyl)โ2โchloroacetamide **2** led to the pteridinone __N(5)__โoxide **4**, while treatment of **2** with Me~3~P yielded the 8โ(chloromethyl)purine **3**. A highโyielding [3+2] dipolar cycloaddition of the __N(5)__โoxid
Ethyl 3-aryl-2-(perfluoroalkanesulfonyl)propenoates were cyclopentadiene. The reactions occurred at room temperature to give [4+2] cycloadducts as racemates. The prepared by the Knoevenagel reaction from various aldehydes and ethyl (trifluoromethanesulfonyl)acetate or endo stereochemistry of the car
