Ueber die Einwirkung von Phosphortrichlorid auf Salicylsäure und auf Phenol;

Structure of products from reactions of phosphorus pentachloride with phenyl salicylate and 2‐hydroxybenzophenone; related compounds. p31 N.M.R. and chemical studies

“…The first of these, structure XIV A , i s historically important in that this was one of the first three (27) The second related cyclic structure is XV A which i s formed by the reaction of phosphorus trichloride and salicylic acid. R. AnschUtz and Emery (32) favored the heterocyclic structure XV A over the acyclic one XV B although they did not have conclusive experimental evidence. L. AnschUtz (the son of R. AnschUtz) later (37) on the basis of studies of the reactions with m i n e s concluded that the acyclic metaphosphite structure ( X V A) was correct.…”

Synthesis, and Some Properties of, Amphiphilic Dinucleoside Phosphate Derivatives of 3′-azido-2′,3′-dideoxythymidine (AZT)

“…Column chromatography was carried out on silica gel 60 (0.04-0.063 nm). The follOWing substances were synthesized in our laboratory according to previously published methods: 4-monomethoxy trityl chloride (Gomberg and Buchler, 1923), 2,4,6-triisopropylbenzenesulfonyl chloride (Lohrmann and Khorana, 1966), 2-chlorophenyl dichlorophosphate (Owens and Reese, 1974), salicylchlorophosphite (Anschutz and Emery, 1887), N 4 _ hexadecyl-5'-0-(4-monomethoxytrityl)-2'-deoxycytidine-3'-0-hydrogenphosphonate (compound 4 in Fig. 1; Schott et al, 1994).…”

Cycloexpansion Reactions in Benzo[e]-1,3,2-diheterophosphorin-4-ones and 4-Oxo-1,3,2-dioxaphospholanes

“…1 Later it was established 2,3 that this compound has a cyclic structure (1) (Figure 1). Derivatives of phosphorous and salicylic acids (2-alkoxybenzo[d]-1,3,2-dioxaphosphorin-4-ones or salicylphosphites) are of interest from a few points of view.…”
