The 1,2-dianion reactivity of the reagent generated from EtMgBr and titanium isopropoxide was illustrated when N-acyl cyanohydrins were used as substrates (>20 examples), giving both aminocyclopropane derivatives and 1,4-dicarbonyl compounds. When the reaction was performed in diethyl ether, 5-hydroxy-1,4-diketones were the main product. Under specific conditions (use of tetrahydrofuran and a bulky

A series of activated and nonactivated esters of 2-furoic and 2-furylacrylicacids were synthesized and examined for antineoplastic activity in the Ehrlich ascites carcinoma screen at 20 mg/kg/d. 2-Furoicacid and 2-furylacrylicacid demonstrated potent activity, as did the methyl and cyanomethyl esters of each series. The vinyl ester of 2-furoicacid possessed antineoplastic activity. However, the
合成了一系列2-糠酸和2-糠基丙烯酸的活化和非活化酯,并在Ehrlich腹水癌筛查中以20 mg / kg / d的剂量检测其抗肿瘤活性。2-糠酸和2-糠基丙烯酸显示出有效的活性,每个系列的甲基和氰基甲基酯也是如此。2-糠酸的乙烯基酯具有抗肿瘤活性。但是,每个系列的乙基和D,L-四氢吡喃基酯在肿瘤筛查中均无活性。
