| 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. |

Enantiospecific Synthesis of (+)-Nemorensic Acid, a Necic Acid Component of the Macropyrrolizidine Alkaloid, Nemorensine.[Pubmed:11674618]
J Org Chem. 1999 Jul 23;64(15):5542-5546.
A concise enantiospecific synthesis of nemorensic acid 3, a necic acid component of the macropyrrolizidine alkaloid Nemorensine 2, isolated from Senecio nemorensis L., is described. Reaction of an epsilon-halo-alpha,beta-unsaturated ester (8), readily accessible from a monoterpene (-)-carvone, with samarium iodide gave a fragmentation product (9), where a carbon-carbon bond cleavage reaction occurred between the gamma and delta positions of the carbonyl group, regioselectively. Deprotection of the silyl group of 9 brought about an intramolecular cyclization to provide tetrahydrofuran derivatives (10), which, upon chemical modification of the side chain, gave nemorensic acid.
