A Direct Approach to Orthogonally Protected α-Amino Aldehydes
作者:Richard Lamb、Vincent L. Revil-Baudard、Samir Z. Zard

O-Neopentyl-xanthate 19 bearing a masked α-amino aldehyde, with the two functional groups orthogonallyprotected, reacts cleanly with many functional alkenes. The radical addition–transfer furnishes densely functionalized adducts that can be further transformed into an array of amino-substituted carbocycles and heteroaromatics. They are also easily converted into imidazolones.
A Radical Bidirectional Fragment Coupling Route to Unsymmetrical Ketones

日期:2016.7.13
A powerful strategy for the regioselective bidirectional synthesis of unsymmetrically substituted ketones is described, relying on the fact that the exchange of a xanthate is much faster than the radical addition to an unactivated alkene. The use of an alkene as the formal "alkylating" agent associated with the tolerance for numerous functional groups and the mildness of the experimental conditions

Convergent Route to β-Amino Acids and to β-Heteroarylethylamines: An Unexpected Vinylation Reaction
作者:Xuan Chen、Samir Z. Zard
DOI:10.1021/acs.orglett.0c01087
日期:2020.5.1
Various protected β2-amino acids can be prepared by radicaladdition of β-phthalimido-α-xanthyl propionic acid, both as the free acid or as the ethyl ester. Successive radicaladditions provide access to more complex structures. In the case of the free acid, addition to certain heteroaromatics leads directly to β-heteroarylethylamines through spontaneous decarboxylation of the intermediate adduct.
