Chemical Biology &Drug Design, Volume 108, Issue 4, October 2026.A series of 18 pyrimidine nucleoside dimers analogues with a short 1,4‐disubstituted 1,2,3‐triazole linkage were synthesized using a click chemistry approach (CuAAC). Analysis of the obtained products was conducted utilizing 1D/2D NMR spectroscopy (1H, 13C, 19F, 15N, and 29Si), mass spectrometry (ESI‐MS), and high‐performance liquid chromatography ...

A Novel Cycloaddition Reaction of Thermally Generated Sulfenes
CHIMIA, 1992 The highly strained ?-sultine 4, resulting from the addition of SO2 to benzobenzvalene, is shown to undergo a thermal cycloreversion which gives 1H-indene-1-thiocarbaldehyde dioxide (6) as an intermediate and subsequently 1H-indene-1 ...
