Ethyl geranate

The 5 (or 6)HF Et3N system reacts with a variety of branched alkenes to give tertiary alkyl fluorides. Hydrofluorination of dienes proceeds at the more reactive C = C bond selectively. Thus, ethyl geranate (1) and ethyl nerolate (2) react with 5HF EtaN at the noncon-... [Pg.107]

Ethyl geranate (50) has been synthesized highly stereoselectively (Scheme 5).136 An alternative route to the ester (51) by y-alkylation of 2-butynoic acid has been... [Pg.17]

Thermolysis of the sulfone 58 gave 58% of a mixture of geraniol (25) and nerol (27) ethyl ethers. Starting from senecioic acid (59), Katzenellenbogen has continued studies of the addition of prenyl halides (15, R = halogen) to the dianion in presence of copper. Copper ion also influenced the addition of prenyl bromide (15, R = Br) to the anion of the V-methylamide of 59, its presence transforming a yield of 98% of the a-addition product to 83% of the y-product, geranic acid V-methylamide [as a mixture of (Z)- and ( )-isomers]. ... [Pg.288]

Ethyl geranate has been prepared stereoselectively under phase-transfer conditions by prenylation of ethyl -3-methyl-4-benzenesulphonylbut-2-enoate and desulphurization. Biomimetic synthesis of (39) from dimethylallyl acetate and isopentenyl acetate (1 3) catalysed by LiC104-Ac0H has been examined the corresponding alcohol (40) is obtained efficiently from isopentenyl acetate by... [Pg.30]

A total synthesis of ethyl geranate (28) makes use of the addition of ethyl 4-bromo-3-methylbut-2-enoate (29) to the nickel carbonyl complex (30) of prenyl bromide. Geranyl acetate and the ethyl ether were made in a similar way. ... [Pg.15]
