unidentified alcohol were produced in minor amounts. A methyl ether corresponding to HSQ was detected when methanol was present in the incubation buffer. These compounds are the expected "solvolysis" products from PSPP. They provide strong support for mechanisms that propose cyclopropylcarbinyl cations as intermediates in the SQase-catalyzed rearrangement of PSPP to SQ and unambiguously demonstrate that the

of squalene; and rillingol (ROH), a cyclopropylcarbinyl alcohol formed by addition of water to the tertiary cyclopropylcarbinyl cation previously proposed as an intermediate in the rearrangement of PSPP to SQ (Poulter, C. D. Acc. Chem. Res. 1990, 23, 70-77). The structure and absolute stereochemistry of the tertiary cyclopropylcarbinyl alcohol were established by synthesis using two independent routes

Incubation of farnesyl diphosphate with recombinantyeastsqualenesynthase in the absence of NADPH gives a mixture of triterpene hydrocarbons and alcohols, including botryococcene-like compounds with 1′−3 linkages between the farnesyl units. One of these molecules has an unusual cyclopentane structure similar to those recently reported in plant extracts and lakebed sediments.
