The Effect of Root Canal Cleansing on the Retention of Glass Fiber-reinforced Posts
… conditioning with solutions such as EDTA or MTAD results in removal of smear layer and might improve the retention of posts to root canal dentin. Therefore, the purpose of this study was to investigate the effect of cleansing the post space with MTAD or EDTA on the bond strength of glass …

Arenophile-mediated dearomative functionalization of unactivated arenes
… are reported using an “arenophile” called MTAD. Arene-arenophile cycloadducts are formed by irradiation of mixtures of unactivated arenes and MTAD at cryogenic temperatures with visible light. These cycloadducts are subsequently used as substrates in metal-catalyzed transformations. In …

Dearomative reduction of arenes through the use of arenophiles & studies towards the synthesis of cardiotonic steroids calotropin and calactin
… of arenes through the use of N,N-arenophile, MTAD, was developed. Cheap feedstock arenes undergo photocycloaddition with MTAD, and the cycloadduct can be treated further to furnish novel 1,3-cyclohexadienes or 1,4-diamino-2- cyclohexenes. The utility of this method is shown in the synthesis of …

Dearomative functionalization of simple arenes: Reduction and palladium-catalyzed syn-1,4-aminofunctionalizations
… such as N-methyl-1,2,4-triazoline-3,5-dione (MTAD), which undergo a visible- light-mediated formal [4+2] para-cycloaddition with simple arenes. The resulting dearomatized arene-arenophile cycloadduct possesses multiple functional handles, which can be further elaborated in situ to a variety of …

Total synthesis enabled by nickel-catalyzed transformations: Dearomative carboamination and methylenecyclopropane annulation
… ability of N-methyl-1,2,4-triazoline-3,5-dione (MTAD) to undergo a [4+2] cycloaddition with benzene to form an intermediary cycloadduct that can then be subjected to a transition metal and nucleophile to form the requisite 1,2-trans-carboaminated product. Chapter 2 describes our efforts to …
