HIGHLY EFFICIENT TOTAL SYNTHESIS OF MANOALIDE AND SECO-MANOALIDE VIA Pd(0) CATALYZED COUPLING OF ALLYLHALIDE WITH CO AND 2-SILYL-4-STANNYLFURAN

Katsumura, Shigeo,Fujiwara, Shinya,Isoe, Sachihiko

, p. 1173 - 1176 (2007/10/02)

Total synthesis of manoalide and seco-manoalide from an allylchloride derivative was achieved by 6 steps in 56.4percent overall yield by Pd(0) catalyzed coupling with CO and 2-trimethylsilyl-4-tributylstannylfuran followed by chemoselective oxidation of 2-trimethylsilylfuran with 1O2.
