IMPROVED SYNTHESIS OF (+/-)-AR-TURMERONE VIA ORGANOTIN REAGENTS

(+/-)-Ar-turmerone has been obtained alternatively from p-methylacetophenone and p-bromotoluene with ethoxymethyltributyltin of α-ethoxycrotyltributyltin and isobutenyltributyltin as key reagents.The overall yields lie in the range 49-60percent.

Facile Regio- and Stereo-specific Allylic Oxidation of gem-Dimethyl Olefins via Addition of Benzenesulphenyl Chloride. Synthesis of Allylic Oxygenated Terpenes

Novel and facile terminal trans-allylic and internal allylic oxidations of the gem-dimethyl olefin terminus of the terpenoids (1) are described which take place site-, regio-, and stereo-specificially via the same intermediate adduct between benzenesulphenyl chloride and (1).By this method, the allylic oxygenated terpenes (+/-)-nuciferal (11), (+/-)-ar-turmerone (12), (+/-)-ipsdienol (3c), neotorreyol (2e), (+/-)-6-hydroxydendrolasin (3e), and 6-oxodendrolasin (14) were synthesized.
