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.
About Packaging 1. The packaging of the product may be reversed during transportation, cause the high purity compounds to adhere to the neck or cap of the vial.Take the vail out of its packaging and shake gently until the compounds fall to the bottom of the vial.
2. For liquid products, please centrifuge at 500xg to gather the liquid to the bottom of the vial.
3. Try to avoid loss or contamination during the experiment.

Total synthesis of the akuammiline alkaloid picrinine.[Pubmed:24597784]

J Am Chem Soc. 2014 Mar 26;136(12):4504-7.

We report the first total synthesis of the complex akuammiline alkaloid Picrinine, which was first isolated nearly five decades ago. Our synthetic approach features a concise assembly of the [3.3.1]-azabicyclic core, a key Fischer indolization reaction to forge the natural product's carbon framework, and a series of delicate late-stage transformations to complete the synthesis. Our synthesis of Picrinine also constitutes a formal synthesis of the related polycyclic alkaloid strictamine.

Fischer Indolizations as a Strategic Platform for the Total Synthesis of Picrinine.[Pubmed:26134260]

J Org Chem. 2015 Sep 18;80(18):8954-67.

Picrinine, which is a member of the akuammiline family of alkaloids, was first isolated in 1965 from the leaves of Alstonia scholaris. The natural product possesses a daunting polycyclic skeleton that contains a furanoindoline, a bridged [3.3.1]azabicycle, two N,O-acetal linkages, and six stereogenic centers. These structural features render Picrinine a challenging and attractive target for total synthesis. This paper provides a full account of our synthetic forays toward Picrinine, which culminates in the first total synthesis of this long-standing target. Central to the success of our approach is the use of the Fischer indolization reaction to introduce the C7 quaternary stereocenter and the indoline nucleus of the natural product's scaffold. We probe some of the subtleties of this classic transformation by examining some of the most complex Fischer indolization substrates to date. Additionally, we describe various roadblocks encountered in our experimental efforts, which were successfully overcome to complete the total synthesis of Picrinine.
