, p. 848 - 849 (2007/10/02)
A simple route for the synthesis of (S)-(Z)- and (S)-(E)-14-methyloctadec-8-en-1-al (Ia and Ib) has been developed.The achiral acetylene (9) is alkylated with the chiron bromide (S)-5 in the presence of BuLi as the base to give 10.This on subsequent functionalisation furnishes both Ia and Ib.
