Garg, Yuvraj,Gahalawat, Suraksha,Pandey, Satyendra Kumar
, p. 38846 - 38850 (2015/05/20)
A simple and highly efficient synthetic approach to enantiopure 2-alkyl substituted tetrahydroquinoline 1 skeleton from aldehydes as starting materials and its application to the total synthesis of (+)-angustureine 2 is described. Key transformations incl
Synthesis of substituted α,β-unsaturated δ-lactones from vinyl tellurides
Oliveira, Juliana M.,R. Freitas, Juliano C.,Comasseto, Jo?o Valdir,Menezes, Paulo Henrique
experimental part, p. 3003 - 3009 (2011/04/27)
A new approach for the synthesis of α,β-unsaturated δ-lactones, a unit present in many natural products with interesting biological activities is described. The approach was based on the use of a vinyl telluride, and it is complementary to the methods usi
A route to 1,2-diols by enantioselective organocatalytic α-oxidation with molecular oxygen
Ibrahem, Ismail,Zhao, Gui-Ling,Sundén, Henrik,Córdova, Armando
, p. 4659 - 4663 (2007/10/03)
A route to 1,2-diols by the direct organocatalytic enantioselective α-oxidation of aldehydes using molecular oxygen is presented. Protected commercially available chiral pyrrolidines catalyze the asymmetric α-oxidation of aldehydes with singlet molecular oxygen with high enantioselectivity to furnish the corresponding diols after in situ reduction in high yield with up to 98% ee. Electrophilic singlet molecular oxygen was photo or chemically generated ('dark' 1O2).
