Practical and efficient synthesis of N-halo compounds
Zhong, Yong-Li,Zhou, Hua,Gauthier, Donald R.,Lee, Jaemoon,Askin, David,Dolling, Ulf H.,Volante, Ralph P.
, p. 1099 - 1101 (2005)
A practical and efficient synthesis of N-halo compounds is described. Treatment of primary and secondary amines or amides with sodium hypohalite in the presence of tert-butanol and acetic acid afforded N-halo compounds in 90-100% yield.
N,N′-dichlorobis(2,4,6-trichlorophenyl)urea (CC-2): An efficient reagent for N-chlorination of amino esters, amide, and peptides
Sathe, Manisha,Karade, Hitendra,Kaushik, Mahabir Parshad
, p. 996 - 997 (2007)
A simple, efficient, and rapid protocol for N-chlorination of various protected amino esters, amides, and peptides has been described. N,N′-dichlorobis(2,4,6-trichlorophenyl)urea has been used as a chlorinating agent and transformation takes place rapidly in mild conditions with quantitative yields. Copyright
New protocol for efficient N-chlorinations of amides and carbamates
Larionov, Oleg V.,Kozhushkov, Sergei I.,De Meijere, Armin
, p. 1916 - 1919 (2003)
N-Chlorination of various amides, carbamates and lactams with inexpensive and stable calcium hypochlorite on moist alumina proceeds smoothly and efficiently, e.g. the technically important 1-chlorohexahydroazepin-2-one (3-Cl) and 1-chloropyrrolidin-2-one (7-Cl) were obtained in 95 % and 98% yield, respectively. Excellent results were also observed for the N-chlorination of protected amino acid esters with a cyclopropane moiety to give derivatives such as methyl (tert-butoxycarbonylchloroamino)cyclopropylacetate (1-Cl), methyl (benzyloxycarbonylchloroamino)cyclopropylacetate (2-Cl), methyl 1-(tert-butoxycarbonylchloroamino)cyclopropanecarboxylate (5-Cl) and methyl trans-2-(tert-butoxycarbonylchloroamino)cyclopropanecarboxylate (6-Cl) in 99%, 96%, 90% and 97% yield, respectively.
Algae-fungicide and algae-sterilization method

Paragraph 0070, (2017/03/08)
This invention relates to an algicide of excellent water solubility, low cost and excellent handling that is characterized in containing N-chloro-2-pyrrolidinone, as well as to an algicidal/microbicidal agent characterized in containing one or more compounds selected from cyclic N-chloro compounds and N,N'-dichloro compounds represented by formula (1). (1) (In the formula, X represents a methylene group, secondary amino group, or N-chloro group, and R represents a C2-5 alkylene group, provided that when X is an N-chloro group, R is a C2-3 alkylene group.)
PROCESS FOR ASYMMETRIC SYNTHESIS OF HEXAHYDROPYRIMIDO[1,2-A] AZEPINE-2-CARBOXAMIDES AND RELATED COMPOUNDS
-
Page/Page column 36; 38, (2010/11/08)
Processes for asymmetric synthesis of 1O(S)-amino-3-hydroxy-4-oxo-4,6,7,8,9,10-hexahydropyrimido[1,2-a]azepine-2-carboxamides and related compounds are disclosed. The enantiomerically enriched carboxamides are useful as HIV integrase inhibitors and thus are useful for treating HIV infection and AIDS.
Conversion of nucleophilic halides to electrophilic halides: Efficient and selective halogenation of azinones, amides, and carbonyl compounds using metal halide/lead tetraacetate
Kim, Jeum-Jong,Kweon, Deok-Heon,Cho, Su-Dong,Kim, Ho-Kyun,Lee, Sang-Gyeong,Yoon, Yong-Jin
, p. 194 - 200 (2007/10/03)
AlCl3/Pb(OAc)4 and ZnBr2/Pb(OAc) 4 are efficient electrophilic N- and α-C-halogenating agents. A variety of azinones, amides and carbonyl compounds were chemoselectively and regioselectively N-, or α-C-halogenated in good to excellent yield using AlCl3/Pb(OAc)4 and ZnBr2/Pb(OAc)4 in acetonitrile.

Ring contraction of N-chlorolactams, a novel rearrangement
Drouin, Alexandre,Lessard, Jean
, p. 4285 - 4288 (2007/10/03)
Upon photolysis in methylene chloride at -78 °C, different N-chlorolactams underwent a novel ring contraction to the corresponding carbamoyl chlorides, which were converted to the methyl carbamates. The rearrangement is 100% stereoselective, occurring with retention of configuration at the migrating carbon center. The yields of isolated carbamates ranged from 40% to 57%, the other product being the parent lactam, 18% to 38%.
A simple protocol for efficient N-chlorination of amides and carbamates
De Luca, Lidia,Giacomelli, Giampaolo,Nieddu, Giammario
, p. 223 - 226 (2007/10/03)
N-Chlorination of various amides, lactams, and carbamates with very cheap trichloroisocyanuric acid proceeds efficiently under very mild conditions. Excellent results were also observed for the N-chlorination of carbamates of free amino acids.

Curini, Massimo,Epifano, Francesco,Marcotullio, Maria Carla,Rosati, Ornelio,Tsadjout, Andrè
, p. 813 - 814 (2007/10/03)
A new method for the preparation of N-chloroamides, lactams and carbamates using Oxone and sodium chloride supported on wet alumina is described.
