The stereochemical course of the annulation process has been determined by reaction of acryloyl chloride with the morpholine enamine of 4-f-butyl-2-methylcyclohexanone. The bicyclic dione was obtained in 76% yield as a 4 1 mixture of two isomers (Scheme 150). X-ray analysis of the main isomer showed that reaction had occurred by axial attack from the same side as the C-2 methyl group. In order for regeneration of the enamine system to occur under conditions of stereoelectronic control, the intermediate ketene-iminium salt presumably adopts a twist conformation. Cyclization of the ketene...

APc(f-Bu)., (20)s was synthesized as follows 2-amino-9,15,24-tri(f-bu-tyl)phthalocyanine (19) (1.0 g, 1.43 X 10 mol) and triethylamine (1.13 mL, 1.55 X 10 mol) were dissolved in tetrahydrofuran (THF) (50 mL). The solution was cooled in an ice bath and acryloyl chloride (0.3 mL, 3.33 X 10 mol) was added dropwise with stirring. The reaction mixture was stirred at room temperature for 2 h. Removal of the solvent afforded a crude product as an oil, which was purified using column chromatography on an activated alumina column by elution with dichloromethane. APc(/-Bu)3 was isolated by removal of the solvent from the first fraction and recrystallized from chloroform-methanol yield 70%. 

Acryloyl chloride in benzene added slowly during 70 min. to a refluxing soln. of l-morpholino-6-methylcyclohexene in the same solvent, refluxed 21 hrs., and the cooled suspension stirred 3 hrs. with water 1-methylbicyclo [3.3.1] nona-2,9-dione. Y 87%. F. e. s. P. W. Hickmott and J. R. Hargreaves, Tetrahedron 23, 3151 (1967).
