There is described a process for the preparation of compounds of formula (1) starting from the reaction of the compounds of formulae (24), (25) and (26) to form the compound of formula (23), wherein in each case R1, R2 and R3 are each independently of the others an unsubstituted or substituted organic radical; R4 is hydrogen, unsubstituted or substituted C1-C8alkyl, C1-C8alkoxy, phenoxy or benzyloxy, or halogen; Y1 and Y2 are each independently of the other hydrogen or a protecting group, or Y1 and Y2 together are a protecting bridge; and X1 is hydrogen, an organic radical or a cation; and also novel intermediates.
