Asymmetric synthesis of ( - )-7-epiaustraline and (+)-1,7-diepiaustraline
Tang, Minyan,Pyne, Stephen G.
, p. 7818 - 7824 (2003)
A diastereoselective and modular approach to the synthesis of the 3-hydroxymethyl-2,3,5,6,7,7a-hexahydro-1H-pyrrolizine-1,2,7-triol structure, characteristic of several natural pyrrolizidine natural products, has been developed. This approach culminated i
Stereoselective Synthesis of the C(1)?–?C(28) Fragment of Amphidinol 3
Yadav, Jhillu S.,Gopalarao, Yerragorla,Chandrakanth, Dandekar,Reddy, Basi V. Subba
, p. 436 - 446 (2016/07/06)
A stereoselective synthesis of the polyol side chain (C(1)?–?C(28)) of amphidinol 3 has been accomplished following Sharpless epoxidation, Crimmins aldol reaction, Jacobsen kinetic resolution, Sharpless asymmetric dihydroxylation, and our own reaction for
Asymmetric syntheses of all stereoisomers of 3-hydroxyproline; A constituent of several bioactive compounds
Kumar, Togapur Pavan,Chandrasekhar, Srivari
, p. 2889 - 2894 (2012/10/29)
Synthesis of an unusual β-hydroxy-α-amino acid, 3-hydroxyproline, and its derivatives have been achieved enantioselectively by employing Sharpless asymmetric epoxidation and reductive cyclization as the key steps. Georg Thieme Verlag Stuttgart ? New York.
Stereoconvergent synthesis of the C1-C11 and C12-C24 fragments of (-)-macrolactin-A
Yadav,Raj Kumar,Sabitha
, p. 463 - 466 (2008/09/18)
Stereoconvergent syntheses of the C1-C11 and C12-C24 fragments of (-)-macrolactin-A are reported.
A convergent approach for the total synthesis of (-)-synrotolide diacetate
Srihari,Prem Kumar,Subbarayudu,Yadav
, p. 6977 - 6981 (2008/02/13)
A simple carbohydrate based convergent approach towards the total synthesis of (-)-synrotolide diacetate is described employing a Sharpless asymmetric epoxidation, a Grignard assisted lactol opening with a terminal alkyne and a Wittig reaction using the H
A new convergent and stereoselective synthesis of 2,5-disubstituted N-acylpyrrolidines
Banfi, Luca,Basso, Andrea,Guanti, Giuseppe,Riva, Renata
, p. 4331 - 4341 (2007/10/03)
A new synthesis of 2,5-disubstituted N-acylpyrrolidines through an SN2′ reaction promoted by the nitrogen anion of a secondary amide onto an allylic bromide is reported. A moderate stereoselectivity, in favour of the trans heterocycle, was obse
Synthesis of viridiofungin A trimethyl ester and determination of the absolute structure of viridiofungin A
Esumi, Tomoyuki,Iwabuchi, Yoshiharu,Irie, Hiroshi,Hatakeyama, Susumi
, p. 877 - 880 (2007/10/03)
Four diastereoisomeric trimethyl esters of viridiofungin A, a member of novel family of aminoacyl alkyl citrate compounds, were synthesized in a highly stereoselective manner and the absolute configuration of natural viridiofungin A was determined to be 3S,4S,2'S.
Studies Directed Towards the Total Synthesis of Rhizoxin: Stereoselective Synthesis of C-12 to C-18 Segment
Rao, A. V. Rama,Bhanu, Manjunath N.,Sharma, G. V. M.
, p. 707 - 710 (2007/10/02)
Chiral carbinol 5, made by a titanocene mediated ring opening of epoxy alcohol 11, was converted via an intramolecular radical cyclisation into a 'butanolide template' which was then transformed to the C-12 to C-18 segment 2 of rhizoxin (1). Key Words: Butanolide chiral template; Chiral carbinol; Intramolecular radical cyclisation; Vinyl Grignard reaction.
