Oxidative rearrangements of tricyclic vinylcyclobutane derivatives.
Three tricyclic vinylcyclobutanes (3-methylenetricyclo[5.3.0.0(2,6)]decanes 1-3) have been subjected to ionization by photoinduced electron transfer in solution and by X-irradiation in Ar matrices. All three compounds undergo oxidative cycloreversion; the cleavage of the four-membered ring, however, occurs in a different direction depending on the presence of a methyl group in position 6 of the...
متن کاملOxidative Fragmentations and Skeletal Rearrangements of Oxindole Derivatives.
An oxidative sequence for the conversion of oxindoles to structurally distinct heterocyclic scaffolds and aniline derivatives is disclosed by the combination of a copper-catalyzed C-H peroxidation and subsequent base-mediated fragmentation reaction. In contrast to classic enzymatic (i.e., kynurenine pathway) and biomimetic methods (i.e., Witkop-Winterfeldt oxidation) for oxidative indole cleava...
متن کاملSecond-order Derivatives and Rearrangements
Inequality (1.2) is classical and very well known. It has been the object of extensions and variants which can be found in a number of papers and monographs, including [AFLT], [Bae], [BBMP], [BH], [Bro], [BZ], [CP], [E], [H], [Ka2], [Kl], [Ma], [Sp1], [Sp2], [Spi], [Ta1], [Ta5], and [Ta6]. Even if not as popular as (1.2), inequality (1.1) has also been known for a long time, and versions of it ...
متن کاملNovel Tricyclic Cyanopyrrolidine Derivatives as Dpp4 Inhibitors: an Improved Synthesis of Tricyclic Α-cycnopyrrolidine from Camphor
An improved multistep synthesis of tricyclic α-cyanopyrrolidine from camphor is presented. The synthesis was carried out by maintaining the cyano group in the form of an amide and its regeneration after the completion of the necessary chemical transformation of a particular functional group. The tricyclic α-cyanopyrrolidine prepared was used to synthesize two novel compounds of DPP4 (Dipeptidyl...
متن کاملOxidative rearrangements during fungal biosynthesis.
Oxidative rearrangements are key reactions during the biosyntheses of many secondary metabolites in fungi. This review highlights the most important examples of these reactions and aims to draw together key mechanistic themes to allow a better understanding and future exploitation of this key class of fungal catalysts.
