WebMar 2, 2016 · The photodeprotection step of the synthesis has been the most time consuming. The NPPOC photolabile group removal requires a radiant exposure of approximately 6 J/cm 2, which can be achieved with a 75 s exposure using 80 mW/cm 2. Significantly higher irradiances are difficult to achieve because, while the total power …
WebThe photodeprotection at 254 nm was followed by 1 H NMR, indicating the release of phenylpropiolic acid, which further underwent copper-catalyzed decarboxylative cleavage in situ to yield a terminal alkyne, phenylacetylene. In addition, the benzylic position of the NB group was modified with methyl, vinyl, allyl, and phenyl moieties.
