A series of regioisomeric trisadducts of C60 having the positional relationships e and trans-n (n = 2-4) resulting from successive additions of malonates or bis(oxazolines) to [6,6]-double bonds of the fullerene framework was isolated and characterized. The new adducts partly represent examples of unprecedented addition patterns. The addition patterns of the new trisadducts with C2, Cs or C1 symmetry were assigned on the basis of the known positional relationships of the addends in their precursor bisadducts, and those of the C2- or Cs-sym. representatives were verified by NMR anal. The absolute configurations of the adducts with inherently chiral addition patterns could be determined either by comparison of the calculated and exptl. CD spectra of the bis(oxazoline) adducts or with knowledge of the absolute configurations of the chiral bisadduct precursors containing bis(oxazoline) addends. The CD spectra of the pairs of diastereomers with an enantiomeric addition pattern show mirror image behavior and pronounced Cotton effects.

A current trend in organic chem. is the development of highly efficient, environmentally friendly and inexpensive catalysts for asym. transformations. Alk. earth metals, due to their specific chem. properties and abundance in nature, provide promising and challenging catalysts in organic synthesis. This article describes the utilization of alk. earth metals in the development of an effective catalytic system based on calcium salts in combination with Box-type ligands. We disclose asym. 1,4-addition and [3+2] cycloaddition reactions using simple catalytic systems consisting of calcium chloride dihydrate, chiral ligands and tetramethylguanidine. Various Box ligands were synthesized and the most effective proved to be that bearing an indane chiral backbone and a cyano group. Depending on the structure of both glycine Schiff bases and α,β-unsaturated compounds, the corresponding Michael adducts or pyrrolidine derivatives were obtained in moderate to high yields with high enantioselectivities. Modification of the catalytic system by using more Lewis acidic calcium salts such as calcium triflate and neutral Pybox-type ligands allows a tuning of the chemoselectivity and leads to suppression of the [3+2] cycloaddition reactions. Various β-substituted acrylates provided 1,4-addition adducts exclusively in high yields with moderate to high diastereo- and enantioselectivities. This methodol. has broadened a synthetic route to β-branched glutamic acid derivatives and established calcium salts as useful and attractive catalysts for asym. catalysis.

A facile cage-like chiral catalyst for the catalytic enantioselective cyclopropanation of multisubstituted olefins with phenyliodonium ylide malonate was developed. Remarkably, this newly designed and cheap bisoxazoline copper(I) complex resulted in the cyclopropanation of a range of substrates such as terminal, disubstituted, and trisubstituted olefins, giving the desired products in excellent yield (≤99%) with enantioselectivity (up to >99% ee). This protocol provides an efficient method for the synthesis of chiral 1,1-cyclopropane diesters.

Author is Albuquerque, Helio; Carneiro, Liliana; Carvalho, Ana P.; Pires, Joao; Silva, Ana R..

The preparation of multipurpose asym. heterogeneous catalysts based on the immobilization of expensive privileged chiral ligands onto porous supports is essential for their use in industry. The benchmark cyclopropanation of styrene has been performed using a copper(II) complex of a com. chiral bis(oxazoline) anchored onto ordered mesoporous silica materials (including SBA-15) and their carbon replicas (including CMK-3), and for the first time, we also report on the asym. aziridination of styrene by anchored copper(II) bis(oxazoline). All the composites prepared were active and enantioselective in these two organic transformations. In the cyclopropanation of styrene, the best heterogeneous catalyst gave higher enantioselectivities and TON than in the corresponding homogeneous phase reactions. In the aziridination of styrene the enantioselectivities for the best heterogeneous catalysts were similar to the propylated bis(oxazoline). The mesoporous silica, prepared by a straightforward one-pot procedure, was always among the best supports for the functionalized bis(oxazoline) in all the asym. processes studied. However its carbon replica was not a good support for the outcome of these asym. transformations, always yielding the lowest enantioselectivities. Once again the mesoporous materials surface properties were an important factor for the uniform distribution of the homogeneous catalyst, as well as for the course of the asym. organic reactions, together with the pore size. The best results presented herein are comparable to the ones reported for copper(II) bis(oxazoline) (2) immobilized onto other types of porous supports.
