Synthesis of 9Z-9-substituted retinoic acids by palladium catalyzed coupling reaction of a vinyl triflate with alkenyl stannanes.

A Wada et al.

Chemical & pharmaceutical bulletin, 48(9), 1391-1394 (2000-09-19)

Palladium catalyzed cross coupling reactions of a vinyl triflate intermediate and various alkenyl stannanes afforded trisubstituted Z-olefins stereoselectively in high yields. These olefins were then converted to the corresponding 9Z-retinoic acids via Horner-Emmons reaction and subsequent basic hydrolysis in excellent

Synthesis of (-)-muricatacin.

H Makabe et al.

Bioscience, biotechnology, and biochemistry, 57(6), 1028-1029 (1993-06-01)

The synthesis of (-)-muricatacin starting from 1-bromododecane and 2-pentyn-1-ol is described. 2-Pentadecyn-1-ol (4), which was prepared from 1-bromododecane (2) and 2-pentyn-1-ol (3), was converted to epoxy alcohol 6 through a two-step reaction sequence, 6 being successively submitted to tosylation, iodination
