Chirality plays a crucial role in life-sustaining processes, and for this reason asymmetric
synthesis has been a central research theme in many research groups in the field of organic …

Photochemistry, bearing significant applications in natural and man-made events such as
photosynthesis, vision, photolithography, photodynamic therapy, etc., is yet to become a …

The photochemical reaction between an excited state of carbonyl compounds and an alkene
to give the oxetane deriving from a cycloaddition reaction (the Paternò–Büchi reaction) is …

Abstract The [2+ 2] photocycloaddition between an electronically excited carbonyl
compound and an alkene leading to oxetanes (Paternò-Büchi reaction) is one of the most …

Atropisomeric maleimides were synthesized and employed for stereospecific [2+ 2]
photocycloaddition. Efficient reaction was observed under direct irradiation, triplet-sensitized …

A visible light-induced cascade cyclization of thioamides with alkynes was developed to
synthesize 1, 3-thiozoles. The sulfur radical generated from thioamide via the single-electron …

A complementary strategy of utilizing ππ* excited state of alkene instead of nπ* excited state
of the carbonyl chromophore in a “transposed Paternò–Büchi” reaction is evaluated with …

Long-chain alkyl (ie, tetradecyl, hexadecyl, and octodecyl) methacrylate (MC), maleic
anhydride (MA), and methylamidemorpholine (MCNR2) were used in this study to prepare a …

An intramolecular Pauson–Khand reaction with enantioenriched N–C axially chiral N-allyl-N-
(2-alkynylphenyl) sulfonamide derivatives proceeded with complete chirality transfer from …

Conspectus Photochemical transformations are a powerful tool in organic synthesis to
access structurally complex and diverse synthetic building blocks. However, this great …
