| abstract | The invention provides a method of rearranging a compound of formula (I), wherein R and R' are selected independently from hydrogen and C1-12alkyl; and R1 and R2 are selected independently from hydrogen, hydroxy, halo, C1-12alkyl- or aryl carbonate, amino, mono- or di-C1-12alkylamino, C1-12alkyl- or arylamido, C1-12alkyl- or arylcarbonyl, C1-12alkyl- or arylcarboxy, C1-12alkyl- or arylcarbamoyl, C1-12alkyl, C2-12alkenyl, C2-12alkynyl, aryl, heteroaryl, C1-12alkoxy, aryloxy, azido, C1-12alkyl- or arylthio, C1-12alkyl- or arylsulfonyl, C1-12alkyl- or arylsilyl, C1-12alkyl- or arylphosphoryl, and phosphato; to form a compound of formula (II), wherein R, R', R1 and R2 are as defined for formula (I); said method comprising treating the compound of formula (I) with a palladium (0) catalyst and a (diphenylphosphino)nC1-6 alkane, wherein n is an integer of 1-6. The invention also provides methods of making penciclovir and famciclovir using this rearrangement reaction. |
