Intramolecular cyclohexadienone annulations of Fischer carbene complexes: model studies for the synthesis of Phomactins.
The intramolecular cyclohexadienone annulation of chromium carbene complexes is examined as a method to provide general access to the Phomactin family of natural products. The importance of the stereochemistry of the carbene complex and the number of carbons in the tether connecting the carbene complex and the alkyne are probed. Additionally, the degree of the 1,4-asymmetric induction is examined.
متن کاملNew Approach to Nonradiative Intramolecular Transitions
A unified and completely time-independent approach based on Feshbach's formalism for nuclear reactions, in which radiative and nonradiative processes are treated on an equal basis, is used to describe the behavior of isolated molecules in a radiation field. The expressions developed are complete and link excited states of measurable lifetime to resonances arising from the action of Green functi...
متن کاملPhosphine-Catalyzed Enantioselective Intramolecular [3+2] Annulations To Generate Fused Ring Systems
Substantial progress has been described in the development of asymmetric variants of the phosphine-catalyzed intermolecular [3+2] annulation of allenes with alkenes; however, there have not been corresponding advances for the intramolecular process, which can generate a higher level of complexity (an additional ring and stereocenter(s)). In this study, we describe the application of chiral phos...
متن کاملImaging intramolecular coulomb repulsions in multiply charged anions.
The properties of multiply charged anions are dominated by intramolecular Coulomb repulsion (ICR). Using photoelectron imaging, we show the effect of ICR on photoelectron angular distributions for a series of dianions, -O2C(CH2)_{n}CO_{2};{-} (D_{n};{2-}). The observed photoemission band of D_{n};{2-} was due to a perpendicular transition from the charged end group. However, photoemission inten...
متن کاملGold(I)-Catalyzed Inter- and Intramolecular Additions of Carbonyl Compounds to Allenenes
The gold(I)-catalyzed intramolecular reaction of allenes with oxoalkenes leads to bicyclo[6.3.0]undecane ring systems, although in the case of terminally disubstituted allenes, seven-membered rings are formed. The related intermolecular addition of aldehydes to allenenes also gives seven-membered rings.
