Azidoacetates undergo aldol-like reaction with aromatic aldehydes in the presence of sub-stoichiometric amounts of NaOEt. The product azido alcohols (2a)-(2q) may be directly converted to N-BOC phenyl serine analogues
The synthetic utility of tert-butyl azidoacetate (7) on the Hemetsberger-Knittel reaction is described. The following two findings are disclosed by using tert-butyl azidoacetate (7) : i) in the first step for the synthesis of ethyl indole-2-carboxylate 4, the aldol reaction of less reactive aldehydes 1a, b was improved greatly; ii) tert-butyl indole-2-carboxylate 10 becomes readily available from aldehydes.
