IMPROVED SYNTHESIS OF (+/-)-AR-TURMERONE VIA ORGANOTIN REAGENTS
Duchene, Alain,Quintard, Jean-Paul
, p. 873 - 882 (2007/10/02)
(+/-)-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.
RELATIONSHIP GOVERNING THE ALKYLATION OF AROMATIC HYDROCARBONS WITH ALLYL CHLORIDE AND BROMIDE IN THE PRESENCE OF SULFURIC ACID
Magerramov, M. N.
, p. 1485 - 1488 (2007/10/02)
The kinetic relationships governing the alkylation of aromatic hydrocarbons by allyl chloride and allyl bromide in the presence of sulfuric acid were studied.It was established that the reactivity of the aromatic hydrocarbons varies in relation to the "activity" of the allyl halides in the order allyl chloride > allyl bromide > propylene.
TERPENE UND TERPENDERIVATE-IX α-CURCUMEN, β-CURCUMEN UND ar-TURMERON DURCH ALKYLIERUNG VON C5- UND C10-DITHIANEN
Bokel, H. H.,Hoppmann, A.,Weyerstahl, P.
, p. 651 - 654 (2007/10/02)
The dithiane 11 is alkylated with prenyl bromide to give 12.Hydrogenolysis of 12 with Raney-Nickel yields α-curcumene (6), hydrolysis of 12 gives the ketone 13.Prenal dithiane (14) is alkylated with 8 to give 15. ar-Turmerone (16) is formed by hydrolysis of 15.Reaction of 15 with sodium in liquid ammonia leads to a mixture of α-curcumene (6) and β-curcumene (10).
