Borane catalysed ring opening and closing cascades of furans leading to silicon functionalized synthetic intermediates
Autor: Chinmoy K. Hazra, Narasimhulu Gandhamsetty, Sehoon Park, Sukbok Chang
Publikováno v: Nature Communications, Vol 7, Iss 1, Pp 1-9 (2016)
Furans are attractive staring materials in organic chemistry, due to the ease of functionalisation and sourcing from renewable feedstocks. Here the authors show the ring opening of furans to silane intermediates, followed by further conversion to cyc

Brønsted‐Acid‐Catalyzed One‐Pot Synthesis of β,β‐Diaryl Esters: Direct Regioselective Approach to Diverse Arrays of 3‐Aryl‐1‐indanone Cores
Autor: Pragya, Sharma, Neha, Taneja, Sanjay, Singh, Chinmoy K, Hazra
Publikováno v: Chemistry – A European Journal. 29
A three-component, solvent-dependent, Brønsted-acid-catalyzed reaction of benzaldehydes, silyl enolates and arene nucleophiles has been developed for the synthesis of potential drug candidate 3-aryl-1-indanones. This reaction features the formation

Lambert Salt-Initiated Development of Friedel-Crafts Reaction on Isatin to Access Distinct Derivatives of Oxindoles
Autor: Jabir Khan, Aparna Tyagi, Naveen Yadav, Rina Mahato, Chinmoy K. Hazra
Publikováno v: The Journal of organic chemistry. 86(24)
Herein, a mild metal-free and efficacious route for the synthesis of biologically important 3-aryl oxindole derivatives is described. Using Lambert salt-initiated hydroarylation of isatin, a diverse array of monoarylated products, symmetrical/unsymme

Disrotatory Ring-Opening of Furans Gives Stereocontrol
Autor: Sukbok Chang, Chinmoy K. Hazra, Jinhoon Jeong, Hyunjoong Kim, Mu-Hyun Baik
Publikováno v: The Journal of Organic Chemistry. 84:11061-11067
The ring-opening of 2-methylfuran and 2,3-dihydro-5-methylfuran catalyzed by the Lewis acid catalyst tris(pentafluorophenyl)borane in the presence of hydrosilanes was studied using quantum chemical methods. In a previous study, it was suggested that
