One-pot thermally chemocontrolled double Diels-Alder strategies. A route to [4 + 2] functionalisation/[4 + 2] derivatization of C60
(2013)The one-pot double Diels-Alder reactions of 3,4-di(methylene) tetrahydrothiophene-1,1-dioxide using temperature as the only chemocontrol element are described. Zn-dust promoted the 1,4-debromination of 3,4-bis(bromomethy ...

Quantitative preparation of 3,4-di(methylene)tetrahydrothiophene-1,1- dioxide by Zn-induced 1,4-debromination. A valuable 6-C reactive diene in [4+2] cycloadditions with DMAD and [60]fullerene
(2012)Optimum reaction conditions for the quantitative preparation of the highly reactive 3,4-di(methylene)tetrahydrothiophene-1,1-dioxide are described. The method involves the zinc-induced 1,4-debromination of 3,4-bis(bromom ...

A study towards the regioselective synthesis of the e,e,e trisadduct of C60 via the [4+2] Diels-Alder reaction with tethers bearing orthoquinodimethane precursors
(2015)The regioselective synthesis of an e,e,e trisadduct of C60 via the Diels-Alder reaction with orthoquinodimethanes has been attempted employing the tether-directed remote functionalization approach. Opened-structure tether ...

Topochemical transformations of substituted cyclopentanone transition metal adducts
(2002)The application of chelation to transition metal ions as a means of controlling the packing motifs of substituted catechols and of substituted malonates has been studied. Substituted malonates have been shown to be capable ...
