A rapid condensation between lysophosphorylcholine and fatty acids with an easily separable amine base
Acharya, Hukum P.,Kobayashi, Yuichi
, p. 2015 - 2018 (2005)
With 2,6-Cl2C6H3COCl and 1-methylimidazole, the title condensation completed at room temperature within 12 hours, which is shorter time than that with the standard DCC/DMAP system. Use of easily separable 1-methylimidazole from the crude product by chromatography is an additional advantage of the present reagent system. Georg Thieme Verlag Stuttgart.

The synthesis of medium-sized heterocycles possessing a trans double bond is still a challenge. Herein, gold(I)-catalyzed 1,2-acyloxy migration/intramolecular cyclopropanation/ring enlargement cascade reaction of furans has been developed, providing highly efficient access to ten- and eleven-membered heterocycles with a broad substrate scope under mild reaction conditions. The reaction outcome features high chemoselectivity at the C5-position of furan. Moreover, a trans-double bond was embodied in the medium ring system.
One-pot synthesis of the tetracyclic framework of the aromatic erythrina alkaloids from simple furans
Kalaitzakis, Dimitris,Montagnon, Tamsyn,Antonatou, Eirini,Vassilikogiannakis, Georgios
supporting information, p. 3714 - 3717 (2013/08/23)
Conversion of a simple furan into the intact erythrinane skeleton in one synthetic operation has been accomplished. The one-pot reaction sequence begins with singlet oxygen photooxygenation of the furan and proceeds via a 2-pyrrolidinone formation, cycliz
