Cyclization of the diester followed by hydrolysis and decarboxylation gives 2-methyl-5-oxo-8-isopropyl-delta1-decalene which on wittig reaction with methylenetriphenylphosphorane furnishes (+-)-gamma-cadinene. 000038977 590__ $$a#NEWS 000038977 650__ $$aTERPENOIDS 000038977 650__ $$aYIELDS 000038977 650__ $$aPRODUCTION 000038977 691__ $$aA000 000038977 7001_ $$aVig, O.P. 000038977 7001_ $$aChugh, O.P. 000038977 7001_ $$aMatta, K.L. 000038977 773__ $$tINDIAN JOURNAL OF CHEMISTRY (SECTION B: ORGANIC CHEMISTRY, INCLUDINGMEDICINAL CHEMISTRY)$$jv.8(1):29-32$$yIJSBDB$$w40922 000038977 8564_ $$s286872$$uhttp://worldveg.tind.io/record/38977/files/e03151.pdf 000038977 901__ $$a41796 000038977 902__ $$aAV-10 000038977 903__ $$aN 000038977 903__ $$aZ 000038977 904__ $$aM 000038977 905__ $$dHsu, Y.C. 000038977 905__ $$cOK 000038977 906__ $$aNT$40.00$$cBids$$d2010-12-03$$ePV-LIB-1019$$fCash 000038977 907__ $$a1$$d2010-11-15$$eR10082(9648796)$$f2010-11-15$$gNational Cheng Kung University$$hNCKU 000038977 912__ $$e2010-11-15$$kHU 000038977 918__ $$aEn 000038977 980__ $$aLIB
