Inter- and Intramolecular Addition Reactions of Electron-Deficient Alkenes with Alkyl Radicals, Generated by SET-Photochemical Decarboxylation of Carboxylic Acids, Serve as a Mild and Efficient Method for the Preparation of γ-Amino Acids and Macrocyclic Lactones
Inter- and intramolecular additions of alkyl radicals, generated by SET photochemical decarboxylation reactions of free carboxylic acids, to electron-deficientalkenes take place under mild conditions as part of efficient routes for the formation of N-Boc γ-amino acids and macrocyclic lactones.
Synthesis of 23-, 25-, 27-, and 29-Membered (<i>Z</i>)-Selective Unsaturated and Saturated Macrocyclic Lactones from 16- and 17-Membered Macrocyclic Lactones and Bromoalcohols by Wittig Reaction, Yamaguchi Macrolactonization, and Photoinduced Decarboxylative Radical Macrolactonization
A new strategy for the synthesis of 23-, 25-, 27-, and 29-membered (Z)-selective unsaturated and saturated macrocycliclactones from commercially available 16- and 17-membered macrocycliclactones and bromoalcohols by Wittig reaction, Yamaguchi macrolactonization, and photoinduced decarboxylative radical macrolactonization is described. The position of the unsaturated part in the macrocyclic lactones
