Enantioselective organocatalytic fluorination-induced Wagner-Meerwein rearrangement.
Despite the fact that only 21 fluorinated molecules are known to be biosynthesized, it is notable that about 20–25% of all modern pharmaceuticals and agrochemicals incorporate at least one fluorine atom. Nevertheless, the practice of introducing fluorine atoms into bioactive compounds is rather recent, as the first synthetic fluorinated drug, namely 5-fluorouracil, was synthesized as late as in...
متن کاملWagner–Meerwein-Type Rearrangements of Germapolysilanes - A Stable Ion Study
The rearrangement of tris(trimethylsilyl)silyltrimethylgermane 1 to give tetrakis(trimethylsilyl)germane 2 was investigated as a typical example for Lewis acid catalyzed Wagner-Meerwein-type rearrangements of polysilanes and polygermasilanes. Direct 29Si NMR spectroscopic evidence is provided for several cationic intermediates during the reaction. The identity of these species was verified by i...
متن کاملA Theoretical Investigation of Kinetics and Mechanism of Aza-Cope Rearrangement
A theoretical study of the kinetic and mechanism of 3-aug-Cope rearrangement in gas phase was performed usingDET methods at B3LYP levels of theory with 6-3114iG(d,p) bass set at 298.I5K. Equilibrium moleculargeometries and harmonic vibrational frequencies of the reactant, transition state Did product were calculated. Then,rate constant and activation thermodynamics parameters were calculated an...
متن کاملPhotoinduced Brook-Type Rearrangement of Acylcyclopolysilanes
Previously unknown 1,1,4-tris(trimethylsilyl)-4-acyldodecamethylcyclohexasilanes (Me3Si)2Si6Me12(Me3Si)COR (16a, R = tert-butyl; 16b, R = 1-adamantyl) have been synthesized by the reaction of the potassium silanides (Me3Si)2Si6Me12(Me3Si)K with acid chlorides ClCOR, and their photochemical rearrangement reactions have been studied. The molecular structures of 16a,b as determined by single-cryst...
متن کاملSYNTHESIS AND THERMAL REARRANGEMENT OF OXYGEN HETEROCYCLIC SPIRANS
Thermal rearrangement of spirans (14) and (31) yields the xanthones (16,34) and diphenylrnethane (15, 32), respectively. The structure for xanthone (16), isolated from thermolysis, has been established by reduction to xanthene (20) followed by reoxidation to give xanthone (16). Alternatively, methylation of the diphenylmethane (15) followed by heating with selenium dioxide also yields xant...
