Novel method for the synthesis of lenvatinib using 4-nitrophenyl cyclopropylcarbamate and their pharmaceutical salts

Sadineni, Ravi Kumar,Rapolu, Rajesh Kumar,Raju, V. V. N. K. V. Prasada,Srinivasu,Malladi, Sireesha,Mulakayala, Naveen

, p. 1475 - 1483 (2020/11/05)

4-Nitrophenyl cyclopropylcarbamate was deployed as a novel synthon for the synthesis of anticancer drug lenvatinib. 4-Nitrophenyl cyclopropylcarbamate was prepared by the reaction of 4-nitrophenyl chloroformate and cyclopropyl amine in acetonitrile at room temperature. Furthermore, lenvatinib was synthesized by reacting 4-(4-amino-3-chlorophenoxy)-7-methoxyquinoline-6-carboxamide with 4-nitrophenyl cyclopropylcarbamate in good yields. Apart from the synthesis of lenvatinib, citrate, phosphate, malate and oxalate salts of?lenvatinib were also reported in good yields.

A safe and efficient route for the preparation of nitro-, dinitro-, and trinitrophenyl chloroformates

Sedlak, Milos,Pejchal, Vladimir,Imramovsky, Ales,Hanusek, Jiri

supporting information, p. 2365 - 2369 (2013/07/26)

A safe and simple method has been developed for synthesis of chloroformates derived from 2-nitrophenol, 4-nitrophenol, 2,4-dinitrophenol, 2,4,6-trinitrophenol, and pentafluorophenol, the yields being in the range of 72-96%. The method is based on a heterogeneous reaction of the substituted phenol with phosgene dissolved in dichloromethane catalyzed with solid anhydrous potassium carbonate. The synthesis of 2,4,6-trinitrophenyl chloroformate takes place only in the presence of a phase-transfer catalyst, in this case the easily recovered α,ω-dimethoxy poly(ethylene glycol) (PEG; M = 2kDa). The only waste products of the suggested synthesis of the mentioned esters are sodium chloride and potassium chloride. The method markedly reduces the explosion risk connected with drying and handling of salts of mono-, di-, and trinitrophenols and is much more environmentally friendly than the currently used methods.

Synthesis and biological activity evaluation of cytidine-5′-deoxy-5- fluoro-N-[(alkoxy/aryloxy)] carbonyl-cyclic 2′,3′-carbonates

Jhansi Rani,Raghavendra,Kishore,Nanda Kumar,Hema Kumar,Jagadeeswarareddy

experimental part, p. 690 - 696 (2012/09/08)

Capecitabine, an oral prodrug of 5-FU was developed to improve the tumor selectivity and tolerability. To enhance the efficacy of capacitabine, a series of 5′-deoxy-5-fluorocytidine derivatives 5a-e were synthesized. In the present study, we investigated antitumor activity of 5′-deoxy-5- fluorocytidine derivatives both in vivo and in vitro methods. Title compounds were non-mutagenic to Salmonella typhimurium tester strain in Ames test. Compounds 5d and 5e are potent to inhibit the proliferation of NCI-69, PZ-HPV-7, MCF-7 and HeLa cells in MTT assay. In particular, 5d and 5e showed potent antitumor activities against L1210 leukemia cell line. Collectively, these findings suggest that 5d and 5e are more potent anti-cancer compounds than capecitabine.

(Cyclopentadienyl)ruthenium-catalyzed regio- and enantioselective decarboxylative allylic etherification of allyl aryl and alkyl carbonates

Austeri, Martina,Linder, David,Lacour, Jerome

experimental part, p. 3339 - 3347 (2011/02/23)

(Cyclopentadienyl)tris(acetonitrile)ruthenium hexafluorophosphate {[CpRu(NCMe)3][PF6] or (cyclopentadienyl) (I·6-naphthalene)ruthenium hexafluorophosphate {[CpRu(I·6-naphthalene)][PF6]} in combination with a pyridine oxazoline ligand efficiently catalyze the decarboxylative allylic rearrangement of allyl aryl carbonates. Good levels of regio- and enantioselectivity are obtained. Starting from enantioenriched secondary carbonates, the reaction is stereospecific and the corresponding allylic ethers are obtained with net retention of configuration. An intermolecular version of this transformation was also developed using allyl alkyl carbonates as substrates. Conditions were found to obtain the corresponding products with similar selectivity as in the intramolecular process. Through the use of a hemi-labile hexacoordinated phosphate counterion, a zwitterionic air- and moisture-stable chiral ruthenium complex was synthesized and used in the enantioselective etherification reactions. This highly lipophilic metal complex can be recovered and efficiently reused in subsequent catalysis runs. Copyright

One-pot radiosynthesis of [13N]urea and [13N] carbamate using no-carrier-added [13N]NH3

Kumata, Katsushi,Takei, Makoto,Ogawa, Masanao,Kato, Koichi,Suzuki, Kazutoshi,Zhang, Ming-Rong

experimental part, p. 166 - 172 (2010/07/02)

The aim of this study was to develop a practical labeling method of [ 13N]ligands using no-carrier-added [13N]NH3 with high specific activity. [13N]urea analogues [13N]1a and [13N]2a or [13N]carbamate [13N]3a were synthesized by reacting isocyanate 5a, carbamoyl chloride 6a or chloroformate 7a with [13N]NH3. The precursors 5a-7a were prepared by treating amines 8a and 9a and alcohol 10a with triphosgene in situ. These reaction mixtures were not purified and were used directly for [ 13N]ammonolysis, respectively. Using the one-pot method, we synthesized [13N]carbamazepine ([13N]4), a putative positron emission tomography ligand for brain imaging. Copyright
