A radical relay strategy is described to synthesize functionalized β-amino alcs. This strategy is enabled by photoredox-catalyzed and nitrogen-centered radical-triggered cascade reactions of styrenes (or phenylacetylenes), enol derivatives, and O-acyl hydroxylamines in DMSO. The broad synthetic application of this method is demonstrated by the reaction of structurally diverse reaction components, including complex mol. scaffolds. Multiple functional groups of the resultant highly functionalized β-amino alc. derivatives facilitate their further transformations. In the experiment, the researchers used many compounds, for example, tert-Butyl (3-ethynylphenyl)carbamate (cas: 185619-66-3Recommanded Product: tert-Butyl (3-ethynylphenyl)carbamate).
tert-Butyl (3-ethynylphenyl)carbamate (cas: 185619-66-3) belongs to esters. Volatile esters with characteristic odours are used in synthetic flavours, perfumes, and cosmetics. Certain volatile esters are used as solvents for lacquers, paints, and varnishes. Esters contain a carbonyl center, which gives rise to 120° C–C–O and O–C–O angles. Unlike amides, esters are structurally flexible functional groups because rotation about the C–O–C bonds has a low barrier. Their flexibility and low polarity is manifested in their physical properties; they tend to be less rigid (lower melting point) and more volatile (lower boiling point) than the corresponding amides.
