, p. 12653 - 12656 (2015)
Phosphine-catalyzed [4+1] annulation of 2-tosylaminochalcones with allenoates has been achieved, giving trans-2,3-disubstitued indolines as major diastereoisomers in moderate to good yields.
A new route to 1,2,3-triazole fused benzooxazepine and benzodiazepine analogues through metal-free intramolecular azide-olefin oxidative cycloaddition

supporting information, p. 3769 - 3774 (2021/07/17)
A gold-catalyzed cyclization/cascade skeletal rearrangement of o-cyanophenylalkynones with 3-amino-benzo[d]-isoxazoles has been developed, which provides an approach for synthesizing medium-sized benzolactones. Based on the experimental results, we postul
Transition metal-free approach to azafluoranthene scaffolds by aldol condensation/[1+2+3] annulation tandem reaction of isocyanoacetates with 8-(alkynyl)-1-naphthaldehydes
Dong, Penghui,Majeed, Kashif,Wang, Lingna,Guo, Zijian,Zhou, Fengtao,Zhang, Qiuyu
, p. 4855 - 4858 (2021/05/25)
A transition metal-free aldol condensation/[1+2+3] annulation reaction of isocyanoacetates with 8-(alkynyl)-1-naphthaldehydes has been developed for the general synthesis of azafluoranthenes. This domino reaction enables successive formation of three new bonds and two rings from readily accessible starting materials in a single operation. Furthermore, this methodology can also be utilized to construct chromeno[4,3-c]pyridines and benzo[c][2,6]naphthyridines in moderate yields.
