SYNTHESIS OF DIHYDROPALLESCENSIN D VIA MANGANESE(III) MEDIATED CYCLIZATION OF AN OLEFINIC β-KETO ESTER

Free radical oxidative cyclization of keto ester 5 with manganese(III) acetate and copper(II) acetate gave bicyclodecanone 6 which was transformed into the furanosesquiterpene dihydropallescensin D.

Studies toward synthesis of bioactive labdanes: Efficient synthesis of 9β-carbomethoxy-4 α, 4β, 10β-trimethyl-(trans)- decahydronaphthalen-8-one

Methyl-5-(2′,6′,6′-trimethylcyclohex-2′-enyl) -3-ketopentanoate 10 has been successfully cyclised to 9β-carbomethoxy- 4α,4β,10β-trimethyl-(trans)-decahydro-naphthalen-8-one 1. Out of the different reaction conditions used, stannic chloride in moist dichlo

Synthesis of New Terpene Skeletons by Chemical Cyclization of Epoxy Olefins

Tin(IV) chloride catalyzed cyclization of the epoxy olefin (+/-)-7 gave the octahydroazulene derivative (+/-)-9, the structure of which was solved by X-ray analysis of its derivative (+/-)-11.Titanium(IV) chloride catalyzed cyclization of the epoxy triene (+/-)-18 yielded the hydrobenzindene derivative (+/-)-19 as a mixture of stereoisomers.The structure of (+/-)-19 was solved by X-ray analyses of its drivatives (+/-)-20 and (+/-)-21. - Key Words: Azulenes / Hydrobenzindenes / Terpenes
