Stereocontrolled synthesis of oxygen-bridged polycycles via intermolecular [3+2] cyclization of platinum-bound pyrylium with alkenes.

چکیده
2-(3-Benzyloxy)prop-1-ynyl)benzaldehyde with PtCl(2) in toluene would form Pt-pyryliums that underwent [3+2] cycloaddition with alkenes to the oxygen-bridged (5H-benzo[7]annulen-5-ylidene)platinum(ii) intermediates with good stereoselectivities. Their tandem rearrangement afforded diverse types of polycycles depending on the electronic nature of the alkenes.

Application of a tridentate NHC containing pincer ligand to Pt catalyzed cascade cyclization reactions has allowed for the catalytic, diastereoselective cycloisomerization of biogenic alkene terminated substrates to the their polycyclic counterparts.
متن کاملAnnulated and bridged tetrahydrofurans from alkenoxyl radical cyclization.
4-Pentenoxyl radicals sharing two or more carbon atoms with a cycloalkane cyclize in a predictable manner stereoselectively and regioselectively to afford in solutions of bromotrichloromethane cycloalkyl-fused or -bridged 2-bromomethyltetrahydrofurans in up to 95% yield. Stereoselectivity in alkenoxyl radical ring closures arises from cumulative steric effects. The substituent positioned the cl...

The first and protective group-free total synthesis of (±)-yezo'otogirin C has been achieved from 3-methyl-4-prenylcyclohex-2-enone in eight steps with 23% overall yield. The tricyclic core of (±)-yezo'otogirin C was established via a bioinspired oxidative cascade cyclization strategy using Mn(II)/Mn(III) and O2, followed by reduction of the peroxy-bridged intermediate using thiourea in refluxi...

A four-step stereocontrolled synthesis of polyfunctionalized cis-decalins is described, involving oxidation of 2-methoxyphenol, intermolecular Diels-Alder reaction, olefination, and Cope rearrangement. Application of this efficient strategy to the total syntheses of (()-eremopetasidione, (()-3â-angeloyloxyfuranoeremophilane, and (()-3â-methacryloyloxyfuranoeremophilane was accomplished from cre...
