, p. 266 - 277 (2017/12/06)
Ground breaking clinical therapeutic advances in the treatment of breast cancer (BC) is the introduction of selective estrogen receptor modulators (SERMs). We have expeditiously designed and synthesized indole-xanthendione hybrids by coalescing the indole
Design, synthesis and biological evaluation of novel indole-benzimidazole hybrids targeting estrogen receptor alpha (ER-α)
Singla, Ramit,Gupta, Kunj Bihari,Upadhyay, Shishir,Dhiman, Monisha,Jaitak, Vikas
, p. 206 - 219 (2018/02/10)
In the course of efforts to develop novel selective estrogen receptor modulators (SERMs), indole-benzimidazole hybrids were designed and synthesised by fusing the indole nucleus with benzimidazole. All the compounds were first inspected for anti-prolifera

In the present study, we have designed and synthesized indole derivatives by coalescing the indole nucleus with chromene carbonitrile and dihydropyridine nucleus. Two compounds 5c and 6d were selected from series I and II after sequential combinatorial li
Cycloaddition of in Situ Formed Azaoxyallyl Cations with 2-Alkenylindoles: An Approach to Tetrahydro-β-carbolinones

, p. 2596 - 2599 (2017/05/24)
A novel [3 + 3] cycloaddition between in situ formed azaoxyallyl cations and 2-alkenylindoles has been developed. This concise method allows the efficient construction of a series of tetrahydro-β-carbolinones in good yields under mild conditions. Gram-sca

Jiang, Xiaojian,Zhang, Feng,Yang, Junjie,Yu, Pei,Yi, Peng,Sun, Yewei,Wang, Yuqiang
supporting information, p. 853 - 858 (2017/03/11)
An unexpected fluorination-oxidation of 2-hydroxymethylindole using selectfluor under mild condi-tions without a catalyst is described. This new chemistry allows for efficient and rapid synthesis of various 3-fluoroindole-2-aldehydes and novel quaternary
Facile Synthesis of 3-Halobenzo-heterocyclic-2-carbonyl Compounds via in situ Halogenation-Oxidation
Jiang, Xiaojian,Yang, Junjie,Zhang, Feng,Yu, Pei,Yi, Peng,Sun, Yewei,Wang, Yuqiang
supporting information, p. 2678 - 2683 (2016/09/03)
A facile method to synthesize 3-halobenzo-heterocyclic-2-carbonyl compounds is described. Mechanistic studies suggested that a halo-cyclization process, which generated the unstable spiro-acetal transition state and readily convertible to the corresponding carbonyl compound might be involved. Diverse 3-halobenzo-heterocyclic-2-carbonyl compounds could be synthesized with up to 95 % yield in mild conditions with inexpensive starting materials. (Figure presented.).
Rh(II)-catalyzed intramolecular annulation of N-sulfonyl 1,2,3-triazoles with indole derivatives: A new method for synthesis pyranoindoles
Xie, Hui,Yang, Jian-Xin,Bora, Pranjal Protim,Kang, Qiang
supporting information, p. 3014 - 3021 (2016/05/19)
A direct and highly stereoselective approach for the synthesis of Z-alkenyl-pyranoindoles had been developed by utilizing Rh(II)-catalyzed intramolecular cyclization of N-sulfonyl-1,2,3-triazoles with indole derivatives. A variety of pyranoindoles were obtained in 44-93% yields. Moreover, a more convenient synthesis of pyranoindoles starting from terminal alkyne was realized via a Cu-Rh sequentially catalyzed one-pot cascade reaction.
Zinc-Catalyzed Alkyne Oxidation/C-H Functionalization: Highly Site-Selective Synthesis of Versatile Isoquinolones and β-Carbolines
Li, Long,Zhou, Bo,Wang, Yong-Heng,Shu, Chao,Pan, Yi-Fei,Lu, Xin,Ye, Long-Wu
supporting information, p. 8245 - 8249 (2015/07/07)
An efficient zinc(II)-catalyzed alkyne oxidation/C£H functionalization sequence was developed, thus leading to highly site-selective synthesis of a variety of isoquinolones and β-carbolines. Importantly, in contrast to the well-established gold-catalyzed intermolecular alkyne oxidation, over-oxidation can be completely suppressed in this system and the reaction most likely proceeds by a Friedel-Crafts-type pathway. Mechanistic studies and theoretical calculations are described.
Studies toward the synthesis of (R)-(+)-harmicine
Mo, Fanyang,Li, Fei,Qiu, Di,Zhang, Yan,Wang, Jianbo
, p. 2297 - 2302,6 (2020/09/16)
The study toward the total synthesis of (R)-(+)-harmicine is reported in this paper. The enantioselective synthesis of pyrrolidinone, the main backbone of of (R)-(+)-harmicine, has been completed by the methodology based on photo-induced Wolff rearrangement of α-diazo-β-carbonyl compounds.

Synthesis of carbazoles by gold(I)-catalyzed carbocyclization of 2-(enynyl)indoles
Praveen, Chandrasekaran,Perumal, Paramasivan Thirumalai
scheme or table, p. 521 - 524 (2011/04/17)
A new synthetic protocol for carbazoles through gold(I)-catalyzed intramolecular hydroarylation of (Z)-2-(enynyl)indoles was achieved in good yields. The requisite (Z)-2-(enynyl)indoles were synthesized stereoselectively by trimethylgallium-promoted, Z-selective Wittig olefination of N-alkylindole-2-carboxaldehydes with propargyl ylides. Substrates possessing both alkyl as well as aromatic groups are well tolerated under these reaction conditions. Georg Thieme Verlag Stuttgart.
