在对二甲苯作为敏化剂的存在下,对环己烯和相应的三烷基硼烷的混合物进行辐照,然后用碱性H 2 O 2连续氧化光解产物,可通过立体选择获得顺式-2-烷基环己醇。1-乙基环己烯的类似反应产生2,2-二烷基环己醇。环庚烯还与硼烷反应以提供顺式-2-烷基环庚醇。通过假定高度应变的反式-环己烯或-庚烯为反应性物质来解释这些反应。光化学产生的反式-环-辛-2-烯酮和顺式,反式-环-辛基-2,7-二烯酮与硼热反应,分别得到3-烷基环辛酮和顺式-7-烷基环辛-2-烯酮。cr啶与硼烷的光反应导致还原性烷基化,以相当好的收率得到9-烷基ac啶。
cis-2-Alkylcyclohexanols are obtained stereoselectively upon irradiation of a mixture of cyclohexene and the corresponding trialkylborane in the presence of p-xylene as a sensitizer and upon the successive oxidation of the photolysate with alkaline H2O2. The similar reaction of 1-ethylcyclohexene yields 2,2-dialkylcyclohexanols. Cycloheptene also reacts with the boranes to afford cis-2-alkylcycloheptanols

Enzymes in organic synthesis. 28. Reinvestigation of the horse liver alcohol dehydrogenase-catalyzed reductions of 2-alkylcyclohexanones.Identification of <i>cis</i>-alkylcyclohexanols as minor products

The formation of cis-2-alkylcyclohexanol products from horse liver alcohol dehydrogenase-catalyzed reductions of 2-alkylcyclohexanones has been detected for the first time. The cis-alcohols are minor (<4%) products, with the isomeric trans-products being heavily predominant under all conditions. cis-Alcohol production can be suppressed by suitable manipulation of the reaction conditions.
