A convenient method for the preparation of fluorous tin derivatives for the fluorous labeling strategy.
A convenient method for the preparation of fluorous aryl stannanes was developed as a means of expanding the general utility of the fluorous labeling strategy (FLS). Following the synthesis of a novel fluorous distannane, a palladium-catalyzed cross-coupling reaction was used to prepare the target compounds from aryl halides. The scope of the reaction was investigated by preparing a small libra...
متن کاملD-Glucosamine as a novel chiral auxiliary for the stereoselective synthesis of P-stereogenic phosphine oxides.
D-Glucosamine was successfully employed as a chiral auxiliary for the enantioselective synthesis of phosphine oxides. The influence of the anomeric position was also investigated and revealed the excellent ability of the α-anomer to perform this transformation in a highly selective fashion. The methodology employed consisted of three steps: diastereoselective formation of the oxazaphospholidine...
متن کاملAuxiliary Potentials In Chiral Media
In the present paper, the expressions for scalar and vector potentials in lossless isotropic chiral media are analyzed. Propagating eigenvalues of these potentials are then obtained. Furthermore by decomposition of sources and fields in a chiral medium, we introduce the auxiliary right-and left-handed potentials and find the associated fields. These potentials are used to solve the problem of a...
متن کاملFluorous chiral bisoxazolines: application in copper-catalyzed asymmetric α-hydrophosphonylation.
A copper-catalyzed asymmetric α-hydrophosphonylation of isatins with a novel fluorous bis(oxazoline) as a ligand is presented. The corresponding chiral α(1)-oxindole-α-hydroxyphosphonates were obtained in 30-91% yield with enantioselectivities up to 92%. The fluorous ligand can be easily recovered and reused at least 3 times without a significant loss in its activity.
متن کاملStereoselective and enantioselective synthesis of five-membered rings via conjugate additions of allylsulfone carbanions*
Abstract: This lecture describes some of our studies of lithio derivatives of allyl sulfone carbanions which add α-regioselectively as well as anti diastereoselectively to Michael acceptor olefins. This can be ascribed to chelation in the Michael addition step. When the reaction leads to subsequent ring closure by using a bromoallyl sulfone, the latter acts as a methylenemethane synthon in a (3...
