First regioselective ring opening of serine derived cyclic sulfamidate by hard nucleophiles like ArONa is developed, where β-elimination of serine sulfamidate ester by stronger nucleophiles is overcome by reversal of the electronic effect of the carboxyla

A route for the synthesis of type B-compounds is reported.Compound 5 is a strong fluorescent and is O-selective.Type C-compounds, for example 10a to 10d show a high fluorescence and are O-selective.They are obtained via 6 and 7 (n = 2-4, 6; R = Me, X = F).Boc-serine is O-phosphonylated by the methyl-phophonicacid-esterfluorides, for example 10c. ω-(9-Acridinyl)alkyl-phosphonicacid-alkylesterfluorides, like 22, are available in only moderate yields via 15a-e as intermediates.More but unsuccesful experiments for the synthesis of fluorescent and O-selective acridine compounds are reported shortly.
