ABSTRACT:
.gamma.-Alkylation of 2-butynoic acid utilizing lithium 2,2,6,6-tetramethylpiperidide and 1-bromo-3-methyl-2-butene, followed by esterification of the resulting 7-methyloct-6-en-2-ynoic acid and treatment of the ester with lithium dimethyl cuprate, yields methyl (Z)-3,7-dimethylocta-2,6-dienoate. The ester is reduced to (Z)-3,7-dimethylocta-2,6-dien-1-ol, commonly known as nerol, which is useful as perfume agent.
