Chemistry and Pharmacology
Synthesis of β-Nitroalkenyl-benzylphosphorylderivativesStarting from methoxy-chlormethylbenzaldehydes 2 the benzylphosphonates and -phosphinoxides 3 A, B had been synthesized, which could be transformed via the Schiff-bases 4 A, B to phosphorylated nitrostyrenes 5 A, B and nitropropenylbenzenederivatives 6 A, B. The phosphonoacids 3 Ad, 3 Bd and 6 Ba could be prepared from the corresponding esters by direct acidic hydrolysis or by dealkylation with trimethylsilylbromide and hydrolysis of the trimethylsilylesters respectively.
