Enantioselective Cascade Cyclization/Protodemetalation of Polyenes with N3Pt2+ Catalysts
The combination of the N-based pincer ligand PyBOX with Pt2+ leads to new catalysts for the enantioselective cycloisomerization of dienyl- and trienyl-ols. The mechanistic combination of electrophilic cyclization followed by rapid protodemetalation is surprising and leads to a powerful construct for developing new reactions.
متن کاملAsymmetric oxidative cation/olefin cyclization of polyenes: evidence for reversible cascade cyclization.
The biosynthesis of cyclic terpenes from polyene precursors by cyclase enzymes is one of nature’s most elegant chemical transformations.[1] The ease with which nature creates complex molecular architectures from achiral precursors has motivated efforts to develop similarly powerful synthetic methodologies.[2] Alimited number of asymmetric methods have been developed,[3] including the notable Br...
متن کاملThe Enol Ether Synthesis of Polyenes
Convenient methods for the preparation of 1-alkoxydienes are reviewed. It is shown that 1-alkoxydienes are very reactive and can be successfully used for the synthesis of polyene compounds. These include some important natural products, such as polyene aldehydes, vitamin A aldehyde, the ethers and esters of vitamin A, f3-ionolidenacetaldehyde, f3-C,9-aldehyde and other related compounds. A conv...
متن کاملCatalytic diastereo- and positionselective oxidative mono-cyclization of 1,5,9-trienes and polyenes.
Ruthenium tetroxide (1 mol%) has been used as a catalyst for the oxidative mono-cyclization of 1,5,9-trienes and polyenes. The poly-unsaturated substrates underwent mono-cyclization with a high degree of diastereo- and positionselectivity to produce mono-tetrahydrofuran diols with a varying degree of unsaturation. Up to four new stereogenic centers were created in this single step transformatio...
متن کاملSynthesis and Optical Properties of Terminally Substituted Conjugated Polyenes
Compound 1 reacts with compounds of the transition metals Fe, Ni, Rh, Mn, Cr, or M o to form dark brown to black solids, whose insolubility and relative nonvolatility make their characterization difficult. However, black “FePlo,” formed immediately upon reaction with FeCI, in T H F at room temperature exhibits-like 1 -an IR band at 8 15 cm I, which is evidence for an intact aromatic Ps ring as ...
