Donor-Acceptor Materials Exhibiting Thermally Activated Delayed Fluorescence Using a Planarized N-Phenylbenzimidazole Acceptor
Sauvé, Ethan R.,Paeng, Jaesuk,Yamaguchi, Shigehiro,Hudson, Zachary M.
, p. 108 - 117 (2020)
An N-phenylbenzimidazole constrained in a coplanar fashion with a methylene tether (IMAC) was designed and used to prepare a series of emitters exhibiting thermally activated delayed fluorescence (TADF). Four novel TADF emitters using 9,9-dimethylacridine

, (2018/02/23)
The present invention relates to novel sulfonamide derivatives, to processes and intermediates for preparing them, to plant growth regulator compositions comprising them and to methods of using them for controlling the growth of plants, improving plant tolerance to abiotic stress (including environmental and chemical stresses), inhibiting seed germination and/or safening a plant against phytotoxic effects of chemicals.
Intramolecular conversion of N,N-bis(2-picolyl)ureas to cyclic carbamates
Jakob, Uwe,Bannwarth, Willi
, p. 6340 - 6344 (2015/11/16)
Herein, we present a new methodology for preparing 6-membered ring carbamates from a CuI-promoted cyclization of N,N-bis(2-picolyl)amine substituted ureas. The reactions work best in the presence of up to five-fold excess of CuCl at room temper
Synthesis of 1,4-dihydro-2H-3,1-benzoxazin-2-ones by hydriodic acid mediated cyclization of t-butyl 2-vinylphenylcarbamates
Kobayashi, Kazuhiro,Fukamachi, Shuhei,Konishi, Hisatoshi
experimental part, p. 2301 - 2307 (2011/04/16)
A two-step facile synthesis of 4,4-disubstituted 1,4-dihydro-2H-3,1- benzoxazin-2-ones starting from α-substituted 2-aminostyrenes is described. The method involves the hydriodic acid mediated cyclization of t-butyl 2-vinylphenylcarbamate derivatives, whi
Convenient synthesis of 1,4-dihydro-2H-3,1-benzoxazin-2-ones by iodocyclization of t-butyl 2-vinylphenylcarbamates
Kobayashi, Kazuhiro,Fukamachi, Shuhei,Nakamura, Daizo,Morikawa, Osamu,Konishi, Hisatoshi
, p. 95 - 105 (2008/09/20)
It has been found that t-butyl 2-vinylphenylcarbamate derivatives underwent iodocyclization on treatment with iodine in the presence of sodium hydrogencarbonate to afford 4-iodomethyl-1,4-dihydro-2H-3,1-benzoxazin-2-one derivatives in generally good yields. The reduction of these 4-iodomethyl derivatives with tributyltin hydride gave the corresponding 4-methyl derivatives in good yields.

SAR studies of 6-(arylamino)-4,4-disubstituted-1-methyl-1,4-dihydro-benzo[d][1,3]oxazin-2-ones as progesterone receptor antagonists
Kern, Jeffrey C.,Terefenko, Eugene A.,Fensome, Andrew,Unwallla, Ray,Wrobel, Jay,Zhu, Yuan,Cohen, Jeffrey,Winneker, Richard,Zhang, Zhiming,Zhang, Puwen
, p. 189 - 192 (2007/10/03)
We previously disclosed that 6-aryl benzoxazin-2-ones were PR modulators. In a continuation of this work we examined the SAR of new 6-arylamino benzoxazinones and found the targets 1-25, with an extra amino linker between the pendent 6-aryl groups and ben
