1,3-Dibromo-5,5-dimethylhydantoin is an alkyl chain-based PROTAC linker that can be used in the synthesis of PROTACs[1].
PROTACs contain two different ligands connected by a linker; one is a ligand for an E3 ubiquitin ligase and the other is for the target protein. PROTACs exploit the intracellular ubiquitin-proteasome system to selectively degrade target proteins[1].

1,3-Dibromo-5,5-dimethylhydantoin mediated oxidative amidation of terminal alkenes in water
Org Biomol Chem 2017 Nov 29;15(46):9889-9894.PMID:29143847DOI:10.1039/c7ob02329d.
A variety of terminal alkenes were converted to the corresponding amides in yields of 25 to 86% in water via treatment with 1,3-Dibromo-5,5-dimethylhydantoin, followed by reaction with molecular iodine and aq. NH3 (or amine) in one pot. This metal- and organic solvent-free protocol is not only suitable for styrene derivatives, but also, for the first time, works well on terminal aliphatic alkenes.
Catalyst-Free 1,2-Dibromination of Alkenes Using 1,3-Dibromo-5,5-dimethylhydantoin (DBDMH) as a Bromine Source
J Org Chem 2022 Mar 4;87(5):3177-3183.PMID:35133816DOI:10.1021/acs.joc.1c02906.
A direct 1,2-dibromination method of alkenes is realized using 1,3-Dibromo-5,5-dimethylhydantoin (DBDMH) as a bromine source. This reaction proceeds under mild reaction conditions without the use of a catalyst and an external oxidant. Various sorts of alkene substrates are transformed into the corresponding 1,2-dibrominated products in good to excellent yields with broad substrate scope and exclusive diastereoselectivity. This method offers a green and practical approach to synthesize vicinal dibromide compounds.
Effectiveness of 1,3-dibromo-5,5 dimethylhydantoin on reduction of Escherichia coli O157:H7- and Salmonella-inoculated fresh meat
J Food Prot 2009 Jan;72(1):151-6.PMID:19205477DOI:10.4315/0362-028x-72.1.151.
1,3-Dibromo-5,5-dimethylhydantoin (DBDMH; 25 degrees C) and hot water (85 degrees C) spray treatments were evaluated for efficacy in decontamination of pathogenic bacteria attached to beef carcass surfaces represented by cutaneous trunci (CT) muscle sections and beef hearts. Treatments were evaluated using two different systems, a commercial carcass wash cabinet and a model carcass washer. The effects were measured immediately after treatment and again after 48 h of storage at 4 degrees C. Section of CT and beef hearts were inoculated with bovine fecal solution containing approximately 6 log CFU/cm2 of Escherichia coli O157:H7 and Salmonella. After DBDMH or hot water spray treatments, bacterial populations were enumerated immediately and after storage for 48 h at 4 degrees C. DBDMH treatments reduced aerobic plate counts, Enterobacteriaceae, E. coli O157: H7, and Salmonella by the same or slightly lower amounts relative to hot water treatment. DBDMH reduced aerobic plate counts and Enterobacteriaceae by 2.8 to 3.6 log CFU/cm2, E. coli O157:H7 by 1.6 to 2.1 log CFU/cm2, and Salmonella by 0.7 to 2.3 log CFU/cm2 on CT sections and beef hearts. Hot water treatment reduced aerobic plate counts and Enterobacteriaceae by 3.0 to 4.1 log CFU/cm2, E. coli O157:H7 by 1.8 to 2.3 log CFU/cm2, and Salmonella by 2.5 to 2.8 log CFU/cm2. After 48 h of storage, the reductions of organisms by DBDMH and hot water treatments were not different. This study demonstrated that DBDMH spray washing could be effective as an antimicrobial intervention for beef carcasses and variety meats.
1,3-Dibromo-5,5-dimethylhydantoin as promoter for glycosylations using thioglycosides
Beilstein J Org Chem 2017 Sep 22;13:1994-1998.PMID:29062419DOI:10.3762/bjoc.13.195.
1,3-Dibromo-5,5-dimethylhydantoin (DBDMH), an inexpensive, non-toxic and stable reagent, is a competent activator of thioglycosides for glycosidic bond formation. Excellent yields were obtained when triflic acid (TfOH) or trimethylsilyl trifluoromethanesulfonate (TMSOTf) were employed as co-promoters in solution or automated glycan assembly on solid phase.
