- 3,6-Diisopropyl-2-hydroxypyrazine and 3,6-Diisopropyl-2-pyrazinethiol as Carriers of Some Alkoxycarbonyl Groups
-
Some derivatives of benzyloxycarbonylated 3,6-diisopropyl-2-hydroxypyrazine and 3,6-diisopropyl-2-pyrazinethiol were prepared and shown to be versatile benzyloxycarbonylation reagents for amines and amino acids.It was also ascertained that 3,6-diisopropyl-2-hydroxypyrazine and 3,6-diisopropyl-2-pyrazinethiol serve effectively as carriers of the β,β,β-trichloroethoxycarbonyl group.

- 2-Acyloxypyrazines. Convenient Acylating Agents for Amines
-
2-Acyloxypyrazines were found to be useful acylating reagents for amines.The preference of the acylation was for primary amines rather than secondary ones and also for aliphatic rather than aromatic ones.
