- Description: 3-(Chloromethyl)coumarins, obtained via acid-catalysed cyclisation of salicylaldehyde-derived Baylis– Hillman adducts, have been treated with propargylamine; reaction of the resulting 3-alkynylmethylcoumarins with azidothymidine (AZT) in the presence of a Cu(I) catalyst has afforded a series of cycloaddition products for evaluation, in their own right, as potential dual-action HIV-1 protease and non-nucleoside reverse transcriptase inhibitors, and as scaffolds for further structural elaboration.

- Description: 1H and 31P NMR methods have been used to access rate constants and activation parameters for each of the consecutive second-order silylation reactions involved in the overall transformation (1a→3a→4a), while computational optimisation of the rate constants obtained from the initial, linear phase of each reaction has permitted an excellent fit with the experimental data for the entire course of the reaction.
