—— | 11,12-dehydrocytisine | 155060-68-7 | C11H12N2O | 188.229 |
It was demonstrated that the attack of Grignard reagents such as methyl-, allyl-, and 3,3-dimethoxypropyl magnesium bromides on 11,12-dehydrocytisine occurs on the α-face, to give the corresponding 11α-alkylcytisine. (−)-Camoensine and (−)-camoensidine were synthesized from (−)-cytisine via the Grignard reaction. The absolute stereochemistry of the above alkaloids was confirmed to be 7R, 9R, 11R and 6S, 7R, 9R, 11R, respectively.
