    摘要: A process for the production of a 1,3-oxathiolane sulfoxide of the formula ##STR1## wherein X is an amino group of the formula --NHR, wherein R is hydrogen, phenyl, C.sub.1 -C.sub.8 alkyl, C.sub.3 -C.sub.6 cycloalkyl, nitrophenyl, (C.sub.1 -C.sub.4 alkoxy)phenyl, furfuryl, halophenyl, tolyl, napthyl, biphenyl or hydroxyphenyl; or X is an alkoxy group of the formula --OR.sup.1 wherein R is C.sub.1 -C.sub.6 alkyl,which process comprises oxidizing a 1,3-oxathiolane of the formula ##STR2## wherein X is as defined above, in the presence of an effective amount of aqueous hydrogen peroxide and a sterically-hindered organoselenium compound of the formula ##STR3## wherein R.sup.2 is aryl, mono-, di- or tri-substituted with C.sub.1 -C.sub.3 alkyl,to the produce the 1,3-oxathiolane sulfoxide. This process stereoselectively produces the cis stereoisomer of the 1,3-oxathiolane sulfoxide. Additionally, there is disclosed a novel method for the preparation of 5,6-dihydro-2-methyl-1,4-oxathiin compounds using this process.

    摘要: Farnesene interpolymer comprises units derived from a farnesene (e.g., α-farnesene or β-farnesene) and units derived from at least one vinyl monomer. The farnesene interpolymer can be prepared by copolymerizing the farnesene and at least one vinyl monomer in the presence of a catalyst. In some embodiments, the farnesene is prepared from a sugar by using a microorganism. In other embodiments, the at least one vinyl monomer is ethylene, an α-olefin, or a substituted or unsubstituted vinyl halide, vinyl ether, acrylonitrile, acrylic ester, methacrylic ester, acrylamide or methacrylamide, or a combination thereof.
