Oxidation of α-Cedrene with Lead Tetraacetate

Abstract

Oxidation of α-cedrene with red lead in the presence of acetic anhydride in glacial acetic acid was found to afford several products; 5-cedranone [1], 5-isocedranone [2], 5-acetoxy-5-cedrene [3], 5 α-acetoxy-6-cedrene [4], 6α-cedranal [5], 13-acetoxy-5-cedrene [6]. 6β acetoxycedrane [7] and 5, 6-diacetoxycedrane [8]. Oxidation of α-cedrene with lead dioxide in glacial acetic acid afforded the products [3], [4], [5], [6] and [7]. Coinpounds [1] to [8] were found to possess a inild wood like odor. © 1977, The Chemical Society of Japan. All rights reserved.
