摘要:A solid phase synthetic method for making substituted 1,5-benzodiazepine-2-one or 1,5-benzothiazepine-2-one. The method is useful for synthesis of large numbers of compounds through automated parallel synthesis or combinatorial library generation and is thus important to rapid discovery or new therapeutic agents containing the base structure of 1,5-benzodiazepine-2-one or 1,5-benzothiazepine-2-one.

摘要:The present invention relates to enhancement of the cycle life of a zinc chromium based catalyst used in the synthesis of 2-methylpyrazine by increasing the reaction temperature step-wise, starting from a low temperature, while monitoring the levels of total conversion and selectivity towards pyrazine. The catalyst can be regenerated after each cycle of use without substantial loss of activity.
