摘要:
Disclosed is a process for producing alanylglutamine, which comprises reacting an N-(2-substituted)-propionylglutamine compound represented by the formula (I): ##STR1## where X represents halogen, alkylsulfonyloxy, or substituted or unsubstituted arylsulfonyloxy, with ammonia at a temperature of 60.degree. C. or below.In accordance with the present invention, highly purified alanylglutamine can be produced in a high yield, without racemization.
摘要:
In the formulae, R.sup.1, R.sup.2, and R.sup.3 independently represent lower alkyl or aryl, and R.sup.4 represents lower alkyl.The present invention relates to a process for producing an indolocarbazole derivative represented by Formula (II), comprising the acidic treatment of a silylated indolocarbazole derivative represented by Formula (VI).
