5-Acetoxy-2-phenyl

Werden als Kondensationsmittel fur a-Thiocarbonylamino-carbonsaure-Derivate Carbonsau-reanhydride verwendet, kann es zu einer nachtraglichen O-Acylierung kommen. So handelt es sich bei einer Reihe von Produkten, die aus a-Thiobenzoylamino-carbonsauren und Acelan-hydrid erbalten wurden, nicht wie angegeben691 um 5-Oxo-2-phenyl-4,5-dihydro-l,3-thiazole, sondern um 5-Acetoxy-2-phenyl-l, 3-thiazole690. 

A second paper161 describes the use of the same base in either THF or t-butanol for the elimination of a-acetoxy phenyl sulphones as outlined in equation (68), in essence a reaction sequence very similar to the Julia olefin synthesis (Section III.B.3) except in the method by which the sulphonyl group is finally removed.

The destruction of heterocycles condensed to the 1,2,4-triazine ring can also be treated as a method of substituent modification. For example, the formation of 3-[acetoxy(phenyl)-methyl]-l,2,4-triazines 24 by treatment of [l,2,3]triazolo[5,l-c][l,2,4]triazines with acetic acid,340 and the degradation of the pyrimido[5,4-c]-1.2,4-triazines353 and pyrimido[4,5-e]-1,2,4-triazines to afford 25 and 26, respectively.331 354 Further reactions of this type are discussed in a previous review.8 For a synthesis of l,2,4-triazine-3,5,6-tricarboxylic acid from pyrrolo[2,l-c]benzo-l,2,4-triazine, see also Houben-Weyl, Vol. 4/1 b, p 643.
