Electrochemical oxidations have been previously mentioned.122 A novel application is the regioselective epoxidation (80% conversion 90% selectivity) at the 6,7-bond of geranyl and neryl esters and phenyl sulphones.214 Another is the one-step conversion of olefins into allylic alcohols via electrooxidative-oxyselenylation-deselenylation, e.g. (97)—>(99). This method has been applied to the synthesis of (100) which can be converted (70%) into marmelolactone [(101) from quince], and...

The enzyme catalyzed reactions that lead to geraniol and farnesol (as their pyrophosphate esters) are mechanistically related to the acid catalyzed dimerization of alkenes discussed m Section 6 21 The reaction of an allylic pyrophosphate or a carbo cation with a source of rr electrons is a recurring theme m terpene biosynthesis and is invoked to explain the origin of more complicated structural types Consider for exam pie the formation of cyclic monoterpenes Neryl pyrophosphate formed by an enzyme catalyzed isomerization of the E double bond m geranyl pyrophosphate has the proper geometry to form a six membered ring via intramolecular attack of the double bond on the allylic pyrophosphate unit... 

Acid-catalyzed esterification of nerol and geraniol with acid anhydrides produces the corresponding esters. The acetates and isobutyrates are also avaUable commercial products. U.S. production of neryl acetate [141-12-8] in 1993 was 18 t at a price of 11.56/kg and that of geranyl acetate [105-37-3] was 132 t at a price of 9.86/kg (67). 

A considerable portion of commercially available geraniol is produced by a modified process linalool obtained in a purity of ca. 65% from a-pinene is converted into linalyl borates, which rearrange in the presence of vanadates as catalysts to give geranyl and neryl borates. The alcohols are obtained by hydrolysis of the esters [32]. 

For tertiary alcohols, transition states corresponding to A and B are usually almost isoenergetic (for an exception see ref 40). Thus, thermolysis of the trichloroacetimidic ester of linalool affords a 60 40 mixture of the geranyl and neryl amides28. 

The cyclization of polyolefin terpenes occurs readily once they have been converted into terminal epoxides. The tetracyclic diterpenes 3a- and 3/S-kaurene have been prepared enzymically from chemically synthesized (/ ,5)-14,15-oxidogeranylgeranyl pyrophosphate (42), providing another example of this cyclization. Trimethyl-aluminium can promote the non-enzymic cyclization of the diethyl ester of neryl phosphate (43), presumably a carbonium ion, to 4-t-butyI-l-methylcyclohexene. ... 

Alkenes (e.g. camphene) are readily prepared by the BF3,Et20-catalysed elimination of secondary borate esters.Terminal conjugated dienes may be prepared by Pd(OAc)2-PPh3-catalysed elimination from allyl phenyl ethers or allylic acetates [e.g. geranyl, neryl, and linalyl acetates to form similar mixtures of myrcene (60—74%), trans-ocimene (8—20%), and c -ocimene (14—20%)], and the complex [(i7-CsH5)Cr(NO)2]2 dehalogenates n/c-dihalides (e.g. limonene tetrabromide) without affecting other halides (except for benzyl halides).
