Catalytic asymmetric formal [3+2] cycloaddition of isatogens with azlactones to construct indolin-3-one derivatives
Xie, Lihua,Li, Yi,Dong, Shunxi,Feng, Xiaoming,Liu, Xiaohua
, p. 239 - 242 (2021/01/14)
The chiral amide-guanidine-catalyzed asymmetric formal [3+2] cycloaddition of isatogens with azlactones is presented. This strategy provided a facile and feasible route to chiral indolin-3-one derivatives bearing two contiguous tetrasubstituted stereocent

A one-pot protocol for the synthesis of a tricyclic pseudoindoxyl scaffold from 2-nitroalkynylbenzenes, comprising of an Au(III)-catalyzed nitroalkyne cycloisomerization leading to isatogen and its [3 + 3]-cycloaddition with donor-acceptor cyclopropanes m
AuBr3-catalyzed cyclization of o-(alkynyl)nitrobenzenes. Efficient synthesis of isatogens and anthranils

, p. 5675 - 5677 (2007/10/03)
The cyclization of o-(arylalkynyl)nitrobenzenes was catalyzed by AuBr3 to produce the corresponding isatogens in good to high yields together with small amounts of anthranils. On the other hand, anthranils were obtained selectively when the AuB

A number of 2-arylisatogens (VII) have been prepared starting from o-nitroacetophenones (I).Condensation of I with different aromatic aldehydes (II) gives the corresponding o-nitrochalkones (III) which on epoxidation followed by treatment with BF3-etherat
