3- Ethoxy-2-methyl-2-butanol

The same system was employed in the reduction of 4-phenyl-2-butanone to (S)-4-phenyl-2-butanol using HLADH as well as 5-ADH from Rhodococcus sp. with high enantioselectivity [113]. With pentamethylcyclopentadienyl-4-ethoxy-methyl-2,2 -bipyridinechloro-rhodium(III) as mediator and HLADH as catalyst, after 5 h 70% of 4-phenyl-2-butanone was reduced to (S)-4-phenyl-2-butanol with 65% ee. Using 5-ADH. 76% of the ketone was converted to the (S)-alcohol after 5 h with 77% ee. Furthermore, this system has been applied in an electrochemical EMR with a polymer bound rhodium complex as mediator.

The aroma compounds studied during the biological ageing of Fino wines belong to different chemical families. The higher alcohols determined were methanol, 2-butanol, 1-propanol, isobutanol, 1-butanol, isoamyl alcohols, 1-pentanol, 3- and 4-methyl-l-pentanol, 1-hexanol, 3-ethoxy-l-propanol, Z-3-hexenol, 1-heptanol, 1-octanol, furfuryl alcohol, 2, 3-butanediol, 1-decanol, benzyl alcohol and phenethyl alcohol. 

Enol ethers are more reactive toward formaldehyde and MesAl than simple alkenes. Reaction with dihydropyran gives a 75% yield of a 92 8 mixture of 33 and 34 (See Figure 10). The major product is again formed by cis addition of hydroxymethyl and methyl groups. Quite different results are obtained with acyclic enol ethers. 20 Reaction of ethyl propenyl ether, as a 78 22 cis-trans mixture, with 2 equivalents of paraformaldehyde and 2 equivalents of MesAl at 0 in CH2CI2 gives a 65% yield of an 18 1 mixture of threo- and c yr/ir< -3-ethoxy-2-meAyl-l-butanol (37 and 38). Identical results are obtained from either pure stereoisomer of ethyl propenyl ether.
