Synthesis of 1-hydroxypyrazole glycine derivatives
摘要:
A series of novel alpha-amino acids containing the 1-hydroxypyrazole ring has been prepared by addition of organomagnesium or organolithium intermediates to diethyl N-Boc-iminomalonate as an electrophilic glycine equivalent. Electrophiles, aryl and heteroaryl substituents were introduced in the pyrazole ring. (C) 2002 Published by Elsevier Science Ltd.
