Reaction Steps

Into a 1 liter autoclave, there are introduced: 54.7 g of 2-(cis-2-n-pentenyl)-3-(1-carbethoxy-2-oxopropyl)-1-cyclopentanone and 110 g of distilled water. The autoclave is evacuated and then rapidly heated to 150°C, which temperature is maintained for 3 hours. After cooling and decompression, the mass is extracted with benzene. The benzene solutions are washed with water distilled and rectified to yield 16.2 g of 2-(cis-2-n-pentenyl)-3-(2-oxopropyl)-1-cyclopentanone. Physical constants: b.p.0.5 = 112°-113°C; nD15 = 1.4785. IR Spectrum: 1740, 1715, 1405, 1355, 1155, 970 and 1670 cm-1. NMR Spectrum: 0.94, 2.08 and 5.34. The compound can be represented by the formula ##SPC26##
