Heterocyclisation of α-aminoacids with triethyl orthoformate and sodium azide in acetic acid has been investigated. It has been shown that valine, leucine, methionine, tyrosine, tryptophan, glutamic and 2-amino-2-phenylacetic acids undergo transformation of amine group into tetrazol-1-yl one giving corresponding derivatives of tetrazol-1-ylacetic acid, whereas cystine and cysteic acid do not react under above mentioned conditions. = Исследована реакция гетероциклизации α-аминокислот, триэтилортоформиата и азида натрия в уксусной кислоте. Показано, что в указанных условиях валин, лейцин, метионин, тирозин, триптофан, глутаминовая и 2-амино-2-фенилуксусная кислоты претерпевают трансформацию аминогруппы в 1-тетразолильную с образованием со...
