An asymmetric synthesis of (+)-erysotramidine
Blake, Alexander J.,Gill, Christopher,Greenhalgh, Daniel A.,Simpkins, Nigel S.,Zhang, Fengzhi
, p. 3287 - 3292 (2005)
A new asymmetric total synthesis of the erythrinan alkaloid erysotramidine is described, which uses chiral base desymmetrisation, N-acyliminium addition, and 6-exo-trig radical cyclisation as the key steps. Georg Thieme Verlag Stuttgart.
Total Synthesis of (+)-3-Demethoxyerythratidinone and (+)-Erysotramidine via the Oxidative Amidation of a Phenol
Paladino, Marco,Zaifman, Joshua,Ciufolini, Marco A.
, p. 3422 - 3425 (2015/07/28)
Oxidative amidation chemistry provides a unified route to aromatic Erythrina alkaloids through a sequence that illustrates new principles and improved conditions to effect a crucial eliminative Curtius-Schmidt rearrangement.
Synthesis of the erythrina alkaloid erysotramidine
L'Homme, Chloé,Ménard, Marc-André,Canesi, Sylvain
, p. 8481 - 8485 (2015/03/18)
A concise synthesis of erysotramidine (an alkaloid belonging to the erythrina family) was achieved starting with an inexpensive phenol and amine derivative. The synthesis is based on oxidative phenol dearomatizations mediated by a hypervalent iodine reage
General and efficient strategy for erythrinan and homoerythrinan alkaloids: Syntheses of (±)-3-demethoxyerythratidinone and (±)- erysotramidine
Gao, Shuanhu,Tu, Yong Qiang,Hu, Xiangdong,Wang, Shaohua,Hua, Rongbao,Jiang, Yijun,Zhao, Yuming,Fan, Xiaohui,Zhang, Shuyu
, p. 2373 - 2376 (2007/10/03)
A general and efficient strategy to both aromatic-type and nonaromatic-type erythrinan and homoerythrinan alkaloids has been developed. This approach involves a key two-step sequence, an alkylation of a ketone with various N-substituted iodoacetamides fol
Synthesis of the tetracyclic framework of the erythrina alkaloids using a [4 + 2]-cycloaddition/Rh(I)-catalyzed cascade of 2-imidofurans
Padwa, Albert,Wang, Qiu
, p. 7391 - 7402 (2007/10/03)
Several 2-imido substituted furans were found to undergo a rapid intramolecular [4 + 2]-cycloaddition to deliver oxabicyclo adducts in good to excellent yields. By using a Rh(I)-catalyzed ring opening of the resulting oxabicyclic adduct, it was possible t
Electrophilic-induced cyclization reaction of hexahydroindolinone derivatives and its application toward the synthesis of (±)- erysotramidine
Padwa, Albert,Lee, Hyoung Ik,Rashatasakhon, Paitoon,Rose, Mickea
, p. 8209 - 8218 (2007/10/03)
A convenient synthesis of variously substituted octahydroindolo[7a,1a]- isoquinolinones has been achieved by an acid-induced cyclization of hexahydroindolinones bearing tethered phenethyl groups. The formation of a single lactam diastereomer is the result
Efficient synthesis of (+/-)-erysotramidine using an NBS-promoted cyclization reaction of a hexahydroindolinone derivative.
Lee, Hyoung Ik,Cassidy, Michael P,Rashatasakhon, Paitoon,Padwa, Albert
, p. 5067 - 5070 (2007/10/03)
An NBS-promoted intramolecular electrophilic aromatic substitution reaction of a hexahydroindolinone derivative was used to assemble the tetracyclic core of the erythrinane skeleton. The resulting cyclized product was transformed into (+/-)-erysotramidine
Synthesis of four possible stereoisomers of 1,2-epoxy-3-hydroxy-erythrinans: Total synthesis of an alkenoid-type erythrinan alkaloid, (±)-erythratidine
Hosoi, Shinzo,Nagao, Motoyoshi,Tsuda, Yoshisuke,Isobe, Kimiaki,Sano, Takehiro,Ohta, Tomihisa
, p. 1505 - 1511 (2007/10/03)
Four stereoisomers of 1,2-epoxy-3-hydroxyerythrinans were synthesized and their stereochemistries were determined. The 1,2α-epoxy-3α-alcohol was converted to the alkenoid-type alkaloid, (±)-erythratidine utilizing reductive migration of an α, β-unsaturate
Chiral synthesis of Erythrina alkaloids. I. Total synthesis of (+)-erysotrine via asymmetric Diels-Alder reaction under high pressure

, p. 2087 - 2095 (2007/10/02)
(S)-(+)-3,4-Dimethoxyphenylalanine methyl ester (1b) was converted, in 3 steps, into (5S)-(-)-8,9-dimethoxy-1,5-dimethoxycarbonyl-2,3-dioxo-2,3,5,6-tetrahy dropyrrolo[2,1-a]isoquinoline (2b). Diels-Alder reaction of 2b with 1-methoxy-3-trimethylsilyloxybu
