Abstract

A new process for the selective preparation of a compound of formula (I), wherein R<1> is a straight, branched or cyclic C1-C20 alkyl group, or an arylalkyl wherein aryl is C6 aryl and alkyl is C2-C6 alkyl; R<2> is defined as for R<1>, or is benzyl, hydroxy, or an aminoalkyl group wherein alkyl is a straight, branched or cyclic C1-C20 alkyl; Y is OH, a group OR<1> wherein R<1> is as defined above, or NR<3>R<4> wherein R<3> and R<4> independently are hydrogen, C1-C20 alkyl, or aralkyl wherein aryl is C6 aryl and alkyl is C2-C6 alkyl, as well as products obtained by said process and intermediates for use in the process.
