The article contains the following contents:
We developed three bathochromic, green-light activatable, photolabile protecting groups based on a nitrodibenzofuran (NDBF) core with D-π-A push-pull structures. Variation of donor substituents (D) at the favored ring position enabled us to observe their impact on the photolysis quantum yields. Comparing our new azetidinyl-NDBF (Az-NDBF) photolabile protecting group with our earlier published DMA-NDBF, we obtained insight into its excitation-specific photochem. While the “”two-photon-only”” cage DMA-NDBF was inert against one-photon excitation (1PE) in the visible spectral range, we were able to efficiently release glutamic acid from azetidinyl-NDBF with irradiation at 420 and 530 nm. Thus, a minimal change (a cyclization adding only one carbon atom) resulted in a drastically changed photochem. behavior, which enables photolysis in the green part of the spectrum. In the experiment, the researchers used many compounds, for example, 3-Iodophenol(cas: 626-02-8Category: iodides-buliding-blocks)
3-Iodophenol(cas: 626-02-8) belongs to organic iodides. Alkyl iodides react at a faster rate than alkyl fluorides due to the weak C-I bond.Category: iodides-buliding-blocksIodo alkanes participate in a variety of organic synthesis reactions, which include the SimmonsSmith reaction (cyclopropanation using iodomethane), Williamson ether synthesis, Wittig reaction, Grignard reaction, alkyl coupling reactions, and Wurtz reaction.
