A catalytic approach for the preparation of indolines by dearomatizing cyclization is presented. FeCl3 acts as a catalyst to afford tetracyclic 5a,6-dihydro-12H-indolo[2,1-b][1,3]benzoxazin-12-ones in good yields. The cyclization also proceeds with tosylamides forming C-N bonds in 53 % yield.

Cu(ii)-thiophene-2,5-bis(amino-alcohol) mediated asymmetric Aldol reaction and Domino Knoevenagel Michael cyclization : a new highly efficient Lewis acid catalyst
Al-Majid, Abdullah Mohammed; Alammari, Abdullah Saleh; Alshahrani, Saeed; Haukka, Matti; Islam, Mohammad Shahidul; Barakat, Assem (Royal Society of Chemistry (RSC), 2022)The highly efficient Lewis acid-catalytic system Cu(II)-thiophene-2,5-bis(amino-alcohol) has been developed for enantioselective Aldol reaction of isatin derivatives with ketones. The new catalytic system also proved to ... -

Lignin-based activated carbon-supported metal oxide catalysts in lactic acid production from glucose
Kupila, Riikka; Lappalainen, Katja; Hu, Tao; Romar, Henrik; Lassi, Ulla (Elsevier, 2021)In this study, heterogeneous biomass-based activated carbon-supported metal oxide catalysts were prepared and tested for lactic acid production from glucose in aqueous solution. Activated carbons were produced from hydrolysis ... -
Aliphatic Ketone Claisen Rearrangement : Troubleshooting the Transetherification Step by Identifying a Stable Acid Catalyst
Pihko, Petri M.; Laasonen, Kari; Bruce, Veera Karoliina; Rolig, Aino; Farshadfar, Kaveh (Wiley-VCH Verlag, 2024)After optimization for retention of catalytic activity, 4-chlorobenzoic acid emerged as the optimal catalyst for the aliphatic ketone Claisen rearrangement. The optimal catalyst enables a one-pot, metal-free, catalytic ... -
Influence of Cu:Fe ratio in synthesis of higher alcohols from syngas over CuFeCoK/attapulgite catalysts
Aho, Atte; Lind, Noora; Virtanen, Pasi; Mäki-Arvela, Päivi; Eränen, Kari; Granroth, Sari; Korpelin, Ville; Honkala, Karoliina; Russo, Vincenzo; Simakova, Irina; Murzin, Dmitry Yu. (Elsevier, 2024)Synthesis of higher alcohols from syngas (H2:CO ratio 2 and 1) was performed at 225–300 °C and 30 bar over copper, iron and cobalt containing catalysts supported on attapulgite and promoted with potassium. The Cu:Fe ratio ...
