, p. 615 - 617 (2017/08/30)
[Figure not available: see fulltext.] Synthesis of 2,3,5-trisubstituted furans can be performed at 120°C in DMF using aryl gem-dibromoethenes and ethyl acetoacetate as the starting substrates under the assistance of Ag2CO3–Cs2/
Copper-Catalyzed Coupling of 2-Siloxy-1-alkenes and Diazocarbonyl Compounds: Approach to Multisubstituted Furans, Pyrroles, and Thiophenes
Tan, Wei Wen,Yoshikai, Naohiko
, p. 5566 - 5573 (2016/07/14)
We report herein copper(II)-catalyzed cyclization reactions of silyl enol ethers derived from methyl ketones with α-diazo-β-ketoesters or α-diazoketones to afford 2-siloxy-2,3-dihydrofuran derivatives or 2,3,5-trisubstituted furans, respectively, under mild conditions. The former cyclization products serve as versatile 1,4-diketone surrogates, allowing facile preparation of 2,3,5-trisubstituted furans, pyrroles, and thiophenes.
Tuning radical reactivity using iodine in oxidative C(sp3)-H/C(sp)-H cross-coupling: An easy way toward the synthesis of furans and indolizines
Tang, Shan,Liu, Kun,Long, Yue,Qi, Xiaotian,Lan, Yu,Lei, Aiwen
supporting information, p. 8769 - 8772 (2015/05/20)
Molecular iodine was found to be an effective redox catalyst for the oxidative cross-coupling of carbonyl compounds with terminal alkynes. In this work, we demonstrated that iodine could tune radical reactivity through reversible C-I bond formation for co
