developed to identify protecting group derivatives with superior caging properties. Bulky rests are attached to the cage moiety via Cu‐catalyzed azide–alkyne cycloaddition post‐synthetically on DNA. Interestingly, the decrease in melting temperature upon introducing o‐nitrobenzyl‐caged (NPBY‐) and diethylaminocoumarin‐cages (DEACM‐) in DNA duplexes reaches a limiting value. NMR spectroscopy was used to

日期:——
Effective direct introduction of alkoxy, amido, azido or halogeno functional groups on the benzylic position in hexamethylbenzene was mediated by the N-F reagents F-TEDA-BF4, NFTh, NFSi or FP-B800 in the presence of alcohols, carboxylic acids, cyanides or trimethylsilyl derivatives as sources of an external nucleophile.
