Crystallization-induced diastereomer transformation of 2-quinolone-4-carboxamide followed by stereoselective intermolecular photocycloaddition reaction.
2-Quinolone-4-carboxamide derived from (S)-proline, which exists as a mixture of two diastereomers before crystallization, converged to a single diastereomer by crystallization (CIDT), and the homochirality was transferred by a intermolecular 2 + 2 photocycloaddition reaction with high optical activity.
متن کاملStereoselective intermolecular [2 + 2]-photocycloaddition reactions of maleic anhydride: stereocontrolled and regiocontrolled access to 1,2,3-trifunctionalized cyclobutanes.
Short synthetic sequences commencing with the photosensitized [2 + 2]-cycloaddition reactions of maleic anhydride with either allyl alcohol or propargyl alcohol have been elaborated to provide access to 1,2,3-trisubstituted cyclobutanes with three differentiated one-carbon substituents and complementary stereochemical patterns. These intermediates were used to prepare three discrete stereo- and...
متن کاملThe arene–alkene photocycloaddition
In the presence of an alkene, three different modes of photocycloaddition with benzene derivatives can occur; the [2 + 2] or ortho, the [3 + 2] or meta, and the [4 + 2] or para photocycloaddition. This short review aims to demonstrate the synthetic power of these photocycloadditions.
متن کاملMetal tips on pyramid-shaped PbSe/CdSe/CdS heterostructure nanocrystal photocatalysts: study of Ostwald ripening and core/shell formation.
We report ripening of metal particles anchored on pyramid-shaped heterostructure nanocrystals. The 'intra-particle' ripening results in a large metal tip at one corner with the other three tips vanishing. Investigation reveals that the ripening and core/shell formation affects photocatalytic activities via the Fermi level change.
متن کاملThe double [3 + 2] photocycloaddition reaction.
A remarkable double [3 + 2] photocycloaddition reaction that results in the formation of fenestrane 2 from aromatic acetal 1 is reported. During the formation of 2, four carbon-carbon bonds, five new rings, and seven new stereocenters are created in a one-pot process. The reaction occurs in a sequential manner from the linear meta photocycloadduct 3, while the angular meta photocycloadduct 4 un...
