Diboronic acids (HO)2B·R·B(OH)2(where R = polymethylene, arylene, or thiophen-2,5-diyl) are prepared by reactions of methyl borate with difunctional Grignard reagents and are characterised by the formation of cyclic esters with various diols. The polymethylenediboronic acids are much more resistant to aerial oxidation than are the corresponding alkylboronic acids. All the diboronic acids undergo dehydration
One-step Synthesis of Long-chain Aliphatic α,ω-Dicarboxylic Acids Utilizing the Copper-catalyzed Reaction of β-Propiolactone with α,ω,-Di-Grignard Reagents
Copper-catalyzed reaction of β-propiolactone with α,ω-di-Grignard reagents, followed by esterification gave six-carbon homologated α,ω-dicarboxylic acid esters in good yields.

The title compound, a potential DNA bis-intercalating agent, is synthesized from the novel bis-4H-furo[3,4-b]indole(7) by a double Diels–Alder reaction With benzyne followed by deoxygenation and desulphonation.
标题化合物是潜在的DNA双嵌入剂,是由新型bis-4 H -furo [3,4- b ]吲哚(7)通过与苯炔的双重Diels-Alder反应,然后进行脱氧和脱磺化作用合成的。
Synthesis and antitumor activity of tropolone derivatives. 7. Bistropolones containing connecting methylene chains
Bistropolone derivatives (4-12) containing differing lengths of linkage between the two tropolone rings were prepared and examined for their antitumor activity in in vitro (KB cell) and in vivo (leukemia P388 in mice) systems. Parent compound 3, related compounds previously prepared, and the new compounds 4-12 were evaluated for inhibitory activity against ribonucleotide reductase by indirect means
