| General tips | For obtaining a higher solubility , please warm the tube at 37 ℃ and shake it in the ultrasonic bath for a while.Stock solution can be stored below -20℃ for several months. We recommend that you prepare and use the solution on the same day. However, if the test schedule requires, the stock solutions can be prepared in advance, and the stock solution must be sealed and stored below -20℃. In general, the stock solution can be kept for several months. Before use, we recommend that you leave the vial at room temperature for at least an hour before opening it. |

Enantiospecific total synthesis of (-)-(E)16-epiaffinisine, (+)-(E)16-epinormacusine B, and (+)-dehydro-16-epiaffinisine as well as the stereocontrolled total synthesis of alkaloid G.[Pubmed:12868917]
J Org Chem. 2003 Jul 25;68(15):5852-9.
An efficient strategy is described for the total synthesis of the sarpagine-related indole alkaloids (-)-(E)16-epiaffinisine (1), (+)-(E)16-Epinormacusine B (2), and (+)-dehydro-16-epiaffinisine (4). A key step employed the chemospecific and regiospecific hydroboration/oxidation at C(16)-C(17); this method has also resulted in the synthesis of (+)-dehydro-16-Epinormacusine B (5). The oxy-anion Cope rearrangement followed by protonation of the enolate that resulted under conditions of kinetic control has been employed to generate the key asymmetric centers at C(15), C(16), and C(20) in alkaloid G (7) in a highly stereocontrolled fashion (>43:1). Conditions that favor control of the sarpagine stereochemistry at C(16) vs the epimeric ajmaline configuration at the same stereocenter have been determined. The formation of the required cyclic ether in 4, 5, and 7 was realized with complete control from the top face on treatment of the corresponding alcohols with DDQ/THF or DDQ/aq THF in excellent yields.
Stereospecific, enantiospecific total synthesis of the sarpagine indole alkaloids (E)16-epiaffinisine, (E)16-epinormacusine B, and dehydro-16-epiaffinisine.[Pubmed:12489960]
Org Lett. 2002 Dec 26;4(26):4681-4.
[reaction: see text] The first stereospecific total synthesis of the sarpagine indole alkaloids (E)16-epiaffinisine (1), (E)16-Epinormacusine B (2), and dehydro-16-epiaffinisine (4) has been completed; this method has also resulted in the synthesis of dehydro-16-Epinormacusine B (5). The formation of the required ether in both 4 and 5 was realized with complete control from the top face on treatment of the corresponding alcohols with DDQ/THF in 98% and 95% yields, respectively.
