Photochemistry of 1,3-bis(diazo)indan-2-one: Consecutive decomposition and suppression of a Wolff rearrangement
Murata, Shigeru,Yamamoto, Tsuneyoshi,Tomioka, Hideo
, p. 4013 - 4023 (1993)
The photodecomposition processes of 1,3-bis(diazo)indan-2-one (19) have been investigated by the characterization of reaction products in fluid solutions and by the direct observation of reactive intermediates in matrices at cryogenic temperatures. Irradi
Approach to Chiral 1-Substituted Isoquinolone and 3-Substituted Isoindolin-1-one by Addition-Cyclization Process

An approach to access 1-substituted isoquinolones has been developed through the addition-cyclization of imines with Grignard reagents in the presence of 2,2′-dipyridyl. A number of substituted aromatic magnesium reagents were amenable to this process, and the desired products were obtained with excellent yields and outstanding diastereoselectivities (dr > 99:1). The utility of this convenient approach is demonstrated by the formal synthesis of (S)-cryptostyline II. Moreover, N-methylmorpholine (NMM) was found to be an effective additive for the formation of 3-substituted isoindolin-1-ones using one-pot addition-cyclization-deprotection of imine with Grignard reagents.
Sigmatropic rearrangement of ammonium ylideskey step in the synthesis of methyl 2-formylphenyl acetate
Kowalkowska, Anna,Jonczyk, Andrzej
, p. 3308 - 3317 (2011/09/21)
N-Cyanomethyl-N,N-dimethyl-N-(-methoxycarbonyl)benzylammonium salts 5 were synthesized and treated with different base/solvent systems, giving the products of sigmatropic rearrangements [2,3] 7 and [1,2] 8. In reactions carried out in liquid ammonia, [2,3] rearrangement definitively prevailed. Pure 7(or mixture of 7 and 8) were deprotected to afford methyl 2-formylphenyl acetate (9) in good yield.

PROSTANOIDS. SYNTHESIS OF &α-PENTANORBENZO ANALOGS OF PROSTAGLANDINS
Miftakhov, M. S.,Akbutina, F. A.,Tolstikov, A. G.,Anpilogov, A. P.,Tolstikov, G. A.
, p. 2258 - 2263 (2007/10/02)
The α-pentanorbenzo analogs of prostaglandins were synthesized from o-formylphenylacetic acid, which was obtained by the ozonization of indene under specific conditions.
