1 -Acctyl-3-

A unique isomerization has been observed on heating 5-acctyl-2-(cycloalkylamino)-3//-azepines, e.g. 24, in solution in their respective amines at 170 C.119 Rearrangement, via a 3-azabicyclo[4.1.0]hepta-2,4-diene intermediate, affords the 6-acetyI-3//-azepine, e. g. 26. The process appears to be base-catalyzed as there is no reaction in xylene at 170 C.

A solution of 5-acctyl-5//-dibcnz[ft,/]azcpine (39, R1 = R2 = H R3 = Me 23.5 g, 0.1 mol) in EtOH (70 mL) and KOH (14 g) was heated under reflux for 18 h. The mixture was cooled and the orange-yellow solid removed by filtration. The residue was washed with cold EtOH and then thoroughly with cold H20 until neutral washings were obtained. The crude product was crystallized (first EtOH then benzene) yield 17.3 g (90%) mp 204 206 C.

In 1991, Whitesides etal. reported the first application of aqueous medium Barbier-Grignard reaction to carbohydrate synthesis through the use of tin in an aqueous/organic solvent mixture (Eq. 8.48).106 These adducts were converted to higher carbon aldoses by ozonolysis of the deprotected polyols followed by suitable derivatization. The reaction showed a higher diastereoselectivity when there was a hydroxyl group present at C-2. However, no reaction was observed under the reaction conditions when there was an /V-acctyl group present at the C-2 position. 

Durch Abbau des Disaccharids mit Ninhydrin, bei dem 3-D-Galakto-pyranosyl-D-arabinose erhalten wurde, bewiesen F. Zilliken, P. N. Smith, R. M. Tomarelli und P. Gyorgy (279) ebenfalls, daB A-Acctyl-lactosamin vorliegt. Auch das A-Acetyl-lactosamin wird, ebenso wie die isomere Lacto-A-biose I, von Lactase nicht angegriffen (250). 

The formation of triazoles by acid-catalyzed ring opening and isomerization of various other C4-substituted sydnones has also been explored <2001MI769>. When applied to 3-(2-acetylphenyl)sydnone, conditions that are successful for C4 acylation of other 3-arylsydnones result unexpectedly in the formation of the jV-acctyl-3-methylindazole 72. Initial protonation of the carbonyl in the ortho-acetyl group triggers attack by the N2 position of the sydnone ring and concludes with hydrolysis and loss of carbon dioxide (Equation 3) <1996SC2757>.
