Summary: | 碩士 === 中原大學 === 化學學系 === 85 === Michael addition and Substitution reaction of 1-methoxycarbonyl-2,3,7-triaza bicyclo[3.3.0]oct-2-enes 2a to electron-deficient dipolarphiles(vinyl ketone、ester)、 alkyl halides , give 7-substituted 1- methoxycarbonyl-2,3,7-triaza bicyclo[3.3.0]oct-2-enes 5. 6. in good yields.
Furthermore, 1-methoxycarbonyl-2,3,7-triaza bicyclo[3.3.0] oct-3-enes 7. 8. 9. , are prepared by isomerization of 1-methoxycarbonyl-2,3,7-triaza bicyclo[3.3.0]oct-2-enes 2. 5. 6. .
