We report an iron-catalyzed general functional group protection method with inexpensive reagents. This environmentally benign process does not use acids or bases, and does not produce waste products. Further purification beyond filtration and evaporation is, in most cases, unnecessary. Free COOH and OH groups can be protected in a one-pot reaction.

In a context of growing resistance to classical antifungal therapy, the design of new drugs targeting alternative pathways is highly expected. Benzofuro[3,2-d]pyrimidine derivatives, derived from (?)-cercosporamide, were synthesized and evaluated as potential Candida albicans PKC inhibitors in the aim of restoring susceptibility to azole treatment. Co-administration assay of benzofuropyrimidinedione 23 and fluconazole highlighted a synergistic effect on inhibition of cell growth of a Candida albicans resistant strain.
The synthesis of lactone-bridged 1,3,5-triphenylbenzene derivatives as pi-expanded coumarin triskelions
Hintz, Heather A.,Sortedahl, Nicholas J.,Meyer, Samantha M.,Decato, Daniel A.,Dahl, Bart J.
supporting information, p. 4703 - 4708 (2017/11/17)
Two triply lactone-bridged 1,3,5-triphenylbenzene derivatives with solubilizing moieties have been synthesized in five and six steps from commercially available starting materials. Compounds containing the 1,3,5-triphenylbenzene core with two atom bridges are relatively unknown. This new class of pi-expanded coumarins contain triskelion architectures and X-ray crystallographic studies of one of the triskelions indicates that the 1,3,5-triphenylbenzene core adopts a near-planar geometry. This is the only known example of a two atom-bridged 1,3,5-triphenylbenzene derivative to adopt a planar structure.
Synthesis and antibacterial activity of new symmetric polyoxygenated dibenzofurans

, p. 178 - 187 (2017/10/16)
A series of symmetric polyoxygenated dibenzofurans with 2-methylbutyril moieties at C-4 and C-6 were obtained from commercial phloroglucinol through a sequence of reactions that include monoacylation, iodination, Suzuki-Miyaura coupling, oxidative dimeriz
Microwave-assisted acetylation of phenols without catalyst under solvent free condition
Zhang, Yu-Quan,Li, Yan-Chun,Zhu, Ji-Hua,Li, Zhi-Feng,Guo, Guo-Zhe,Chen, Dong-Ping
, p. 7746 - 7748 (2015/02/02)
Etherification between phenols with acetic anhydride was tested under different conditions. Phenols were efficiently acylated with acetic anhydride to give phenol acetate derivatives in good high yields without catalyst and solventless conditions under microwave irradiation.
Synthesis and antiproliferative activity of benzofuran-based analogs of cercosporamide against non-small cell lung cancer cell lines
Bazin, Marc-Antoine,Bodero, Lizeth,Tomasoni, Christophe,Rousseau, Bénédicte,Roussakis, Christos,Marchand, Pascal
, p. 823 - 832 (2013/10/22)
A novel series of 3-methyl-1-benzofuran derivatives were synthesized and screened in vitro for their antiproliferative activity against two human NSCLC cell lines (NSCLC-N6 mutant p53 and A549 wild type p53). Most promising compounds presented a structural analogy with the west part of cercosporamide, a natural product of biological interest. In particular, compounds 10, 12 and 31 showed cytotoxic activities at micromolar concentrations (IC50 50 values (25-40 μM).
