Imidazole (2) and indole (3a) react with 4-ethoxymethylene-2-phenyl-2-oxazolin-5-one (1b; R2=H) to give 4-(imidazol-1-ylmethylene)- and 4-skatylidene-2-phenyl-2-oxazolin-5-ones (1d and 1e), respectively.Their structure are discussed.

N-Acyl-α,β-dehydrotryptophan (ΔTrp) esters 4a-h were directly synthesized by the reaction of 3--3H-indole (2) with N-acylglycinates 3a-h in resonable yields.Of these, N-formyl-substituted ΔTrp methyl ester (4a) was easily converted into ΔTrp methyl ester (7) in a high yield by acidolysis with dry methanol-hydrogen chloride.Furthermore, 7 was successfully used for the preparation of a dipeptide, N-alanyl-substituted ΔTrp methyl ester (10).
