| 摘要 |
This invention relates to a process of reducing 2,4,5-trialkyl 2,3,4,5-tetrahydropyrimidine and/or 2,5,6,8,9-pentaalkyl 1,3,7-triazabicyclo (3,3,1) non-3-enes to yield 2,4,5-trialkylhexahydropyrimides and/or 2,4,5,6-tetraalkyl-5-(2-azoalkyl) hexahydropyrimidines; and to the cleavage of the above reduced products so as to convert the above hexahydropyrimides from cyclic amines to corresponding linear diamines and triamines. This invention also relates to the products produced by the processes.
