Abstract The oxazoline ring in 4-arylazo-2-aryl-2-oxazolin-5-ones (1) is converted to triazolyl-carbonyl amino acids 2, 4 and 6 by the nucleophiles glycine, anthranilic and p-aminobenzoic acids, respectively. The arylidene derivatives 3 of 2-triazolyl-2-oxazolin-5-one were obtained. Triazolylbenzoxazinones 5, were obtained by the ring closure of the amino acid 4.Grignard's reagent effected ring cleavage of the oxazolinone ring in 4-cinnamylidene-2-aryl-2-oxazolin-5-ones yielding the carbinols 8, the latter cyclizes either in acidic or alkaline medium to afford either benzotropilidenes or oxazolines, respectively.
