Chemistry is traditionally divided into organic and inorganic chemistry. category: Isoxazoles, The former is the study of compounds containing at least one carbon-hydrogen bonds.In a patent，Which mentioned a new discovery about 33282-15-4

Current results identified 4-substituted 2-phenylaminoquinazoline compounds as novel Mer tyrosine kinase (Mer TK) inhibitors with a new scaffold. Twenty-one 2,4-disubstituted quinazolines (series 4-7) were designed, synthesized, and evaluated against Mer TK and a panel of human tumor cell lines aimed at exploring new Mer TK inhibitors as novel potential antitumor agents. A new lead, 4b, was discovered with a good balance between high potency (IC50 0.68 muM) in the Mer TK assay and antiproliferative activity against MV4-11 (GI50 8.54 muM), as well as other human tumor cell lines (GI50 < 20 muM), and a desirable druglike property profile with low log P value (2.54) and high aqueous solubility (95.6 mug/mL). Molecular modeling elucidated an expected binding mode of 4b with Mer TK and necessary interactions between them, thus supporting the hypothesis that Mer TK might be a biologic target of this kind of new active compound.

Atom- and step-economy in photoassisted diversity-oriented synthesis (DOS) is achieved with a versatile oxalyl linker offering rapid access to complex alkaloid mimics in very few experimentally simple steps: (i) it allows for fast tethering of the photoactive core to the unsaturated pendants, especially important in the case of (hetero)aromatic amines – essentially a one-pot reaction with no isolation of intermediates; (ii) the alpha-dicarbonyl tether acts as a chromophore enhancer, extending the conjugation chain and facilitating the “harvest” of the lower energy photons for the primary and secondary photoreactions; (iii) it enhances the quantum yield of intersystem crossing (ISC), i.e., it is capable of sensitizing secondary photochemical processes in the cascade; and (iv) the tether forms an additional heterocyclic moiety, imidazolidine-4,5-dione, a known pharmacophore. The overall photoassisted cascade is an efficient complexity-building process as quantified by computed step-normalized complexity indices, leading to extended polyheterocyclic molecular architectures comparable in complexity to natural products such as paclitaxel while requiring only 2-4 simple synthetic steps from readily available chemical feedstock.

Direct cyclopropylation of arylamines at the 2-position with 1-chlorocyclopropyl phenyl sulfoxides was achieved. The reaction of N-lithio arylamines with cyclopropylmagnesium carbenoids, which are generated from 1-chlorocyclopropyl phenyl sulfoxides with i-PrMgCl via the sulfoxide-magnesium exchange reaction, is the key of this procedure. This method offers an unprecedented way for the synthesis of arylamines having a cyclopropane ring at the 2-position directly from arylamines.

Treatment of allylic alcohols with thiocarbonyldiimidazole generates an unstable O-allyl imidazolyl thione ester, which rearranges spontaneously and in high yield to the corresponding S-allyl imidazolyl thiol ester. Displacement of the imidazole by N-alkylanilines in the presence of a nucleophilic catalyst (HOBt or ECHIA) gives S-allyl N-aryl thiocarbamates in excellent yields (up to 97%) over two steps.
