Thiobenzamide reacts also with a- or -naphthylbromomethylketone to give 2-phenyi-4-a- or /3-naphthylthiazoles (54),... 

For example, 2-phenyl-5-fonnylthiazole treated with AgjO in water and dioxane under basic conditions gives 2-phenyI-5-thia201ecarboxylic acid (29). 

PhenyI-3,3-dichIoro-l-azetine (222) forms a 2 1 complex with silver tetrafluoroborate and 1 1 complexes with silver trifluoromethanesulfonate and with boron trifluoride. The dibromo analogue of (222) affords a similar 2 1 complex with silver tetrafluoroborate (79CB3914).

A 1-2-phenyI shift occurs especially easily. In the acid fission of 2-(a-phenylethyl)-3-isopropyloxazirane (20) aniline was isolated as the sole basic fission component. Of the two available groups,... 

The action of potassium hydroxide on a solution of 2-( -phenyI-cthyl)-3-isopropyloxazirane (20) in glycol solution gives a mixture of acetophenone (0.25 mole), isobutyraldehyde (0.57 mole), and ammonia (0.92 mole). ... 

Stage 2 Preparation of 1 -[2-Phenyi-2-Methoxy]-Ethyi-Piperazine — 210 grams of 2-phenyl-2-methoxy-ethyl bromide and 260 grams of anhydrous piperazine are heated for 5 to 6 hours to reflux in 600 ml of ethanol, 500 ml of ethanol is then distilled off and finally the solvent is removed in vacuo. The residue is taken up in 250 ml of benzene and the piperazine hydrobromide is filtered off. The benzene is removed in vacuo. The oily residue is taken up by 450 ml of water and acidification is effected up to pH = 1 by concentrated HCI.

Monomer I (MAA) was dissolved in methanol and I moI% of crosslinking agent, tetraethyleneglycol dimethylacrylate (TEGDMA) (Polysciences, Inc., Warrington, PA), and I wt% of initiator, 2,2-dimethoxy-2-phenyI acetophenone (DMPA Aldrich, Milwaukee, WI) were added. The solution was cast on glass plates equipped with spacers and reacted under an UV source with an intensity of 1 mW/cm for 30 min. Polymer I (PMAA) was removed from the plates, washed in deionized water to remove all unreacted monomers, cut into discs, and dried in a vacuum oven. 

In contrast, when the same reaction was carried out on 4-(bromomethyIene)-2-phenyI-5(4H)-oxazolone 658 (X = Br) or 4-(iodomethylene)-2-phenyl-5(4//)-oxazolone 658 (X = serendipitous formation of the 2-(halomethyl)spirocy-clopropanes 659 and 660 was observed. Both diastereoisomers of 2,3-methano-methionine 663 and 664 have been prepared from the isolated 2-(bromomethyl)-spirocyclopropane oxazolones, 659 and 660, respectively. The isolated 2-(iodo-methyl)spirocyclopropane oxazolones have been hydrolyzed to furnish the...
