- W977074879 abstract "Precipitons, solubility-based phase tags, can be used in similar fashion to other solution based phase tags without many of the disadvantages. Structures based on azobenzene have been studied as alternatives to stilbene-based precipitons. The double bond between nitrogens in azobenzene can be interconverted between cis and trans by UV irradiation, unlike stilbene which only isomerizes in the cis to trans direction. The analogous nature of azobenzene to stilbene was the basis for the creation and study of possible recyclable alternatives to the studied stilbene orignal. Stilbene-based precipiton reagent tags have also been studied. Previous studies show the effectiveness of precipitons as a substrate tag. To show the precipiton's effectiveness as a reagent scavenger, several carbodiimide-based tags have been synthesized and tested as reagent scavengers. Finally, various sulfoxides tagged with a stilbene-based precipiton have been synthesized in order to demonstrate isolation of small molecules by sublimation from solids. Proof of principle is demonstrated by isomerizing precipiton tagged sulfoxides which are subsequently heated in oil and release several small allyl protected products. These products are isolated and characterized by common methods." @default.
