A mild and green electro-oxidative protocol to construct aromatic esters from methylarenes and alcohols is herein reported. Importantly, the reaction is free of metals, chemical oxidants, bases, acids, and operates at room temperature. Moreover, the design of the electrolyte was found critical for the oxidation state and structure of the coupling products, a rarely documented effect. This electro-oxidative coupling process also displays exceptional tolerance of many fragile easily oxidized functional groups such as hydroxy, aldehyde, olefin, alkyne, as well as neighboring benzylic positions. The enantiomeric enrichment of some chiral alcohols is moreover preserved during this electro-oxidative coupling reaction, making it overall a promising synthetic tool.

Divergent Diels-Alder methodology from methyl coumalate toward functionalized aromatics
Lee, Jennifer J.,Kraus, George A.
supporting information, p. 2366 - 2368 (2013/06/26)
An inverse electron-demand Diels-Alder reaction between methyl coumalate and electron-rich dienophiles produces substituted benzoates. A high-yielding, single-pot procedure transforms readily accessible vinyl ether, ketal, or orthoester dienophiles into functionalized aromatic systems in a versatile route.

Chang, Dong-Jo,Yoon, Eun-Young,Lee, Geon-Bong,Kim, Soon-Ok,Kim, Wan-Joo,Kim, Young-Myeong,Jung, Jong-Wha,An, Hongchan,Suh, Young-Ger
scheme or table, p. 4416 - 4420 (2010/04/05)
Synthesis and biological evaluation of various colchicine analogues through the mixed-lymphocyte reaction (MLR), lymphoproliferation, and inhibitory effects on the inflammatory genes are described. In addition, a new series of immunosuppressive agents developed on the structural basis of colchicine, as well as their structure-activity relationships is reported. The most potent analogue 20a exhibited an excellent immunosuppressive activity on in vivo skin-allograft model, which is comparable to that of cyclosporin A.

Diels-Alder Reactions with 2H-Pyran-2-ones: Reactivity and Selectivity
Effenberger, Franz,Ziegler, Thomas
, p. 1339 - 1346 (2007/10/02)
2H-Pyran-2-ones 1 react with maleic anhydride (2) in a double Diels-Alder reaction to give bicyclooct-2-ene-5,6:7,8-tetracarboxylic dianhydrides 5; the syn/syn structure was established.As expected, the reactivity of 1 was increased by electron donor substituents (OR, alkyl) and diminished by electron withdrawing substituents (CO2R).The steric influence of substituents at C-6 also decrease the reactivity of 1. - Methyl propiolate (6) and phenylacetylene (9) react with 1 to form the Diels-Alder products 7 which suffer CO2 elimination to yield methyl benzoates 8 with low and biphenyls 10 with high regioselectivity, respectively.
