Chamigranes are sesquiterpenoids characterized by a 1,1,5,9-tetramethylspiro[5,5]undecane skeleton, formally obtained by linking the C1-C6 and C6-C11 of farnesane together. They are predominantly isolated from algae. Beta-chamigrene can be found in lovage, which makes beta-chamigrene a potential biomarker for the consumption of this food product. β-chamigrene 3,7,7-Trimethyl-11-methylenespiro[5.5]undec-2-ene beta-Chamigrene Chamigren Chamigrene Spiro[5.5]undec-2-ene, 3,7,7-trimethyl-11-methylene-, (-)- Spiro[5.5]undec-2-ene, 3,7,7-trimethyl-11-methylene-, (R)- C15H24 204.3511 204.187800768 3,7,7-trimethyl-11-methylidenespiro[5.5]undec-2-ene β-chamigrene 18431-82-8 CC1=CCC2(CC1)C(=C)CCCC2(C)C InChI=1S/C15H24/c1-12-7-10-15(11-8-12)13(2)6-5-9-14(15,3)4/h7H,2,5-6,8-11H2,1,3-4H3 WLNGPDPILFYWKF-UHFFFAOYSA-N belongs to the class of organic compounds known as chamigranes.
