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).
用噻吩基溴将二噻吩11烷基化,得到12。用阮内镍对12进行氢解可生成α-姜黄素(6),对12进行水解可得到酮13。用8与烷基二噻吩(14)烷基化得到15。Ar-Turmerone(16)是由15水解而成。的反应15与钠在液氨导致α姜黄烯的混合物(6)和β-姜黄烯(10)。
