Kudelko, Agnieszka,Zieliński, Wojciech,Ejsmont, Krzysztof

, p. 7838 - 7845 (2011/10/12)

New derivatives of 2-(1-amino-1-phenylmethyl)-1,3,4-oxadiazole and 1,2,4-triazin-6-one were synthesised in the reactions of optically active α-aminocarboxylic acid hydrazides and triethyl orthoesters in xylene. The electronic and steric effects of substituents at the α position influencing the formation of five- or six-membered products are discussed.
