Autor: Nimmakayala Raghu, Kukkadapu Ankamma, Neerasa Jayaprakash, Gullapalli Kumaraswamy
Publikováno v: Tetrahedron. 71:5472-5477
A concise linear synthesis of 5′-epi synargentolide-B has been accomplished with i) catalytic asymmetric transfer hydrogenation for the genesis of chirality, ii) regioselective Sharpless asymmetric dihydroxylation iii) a vinylogous Mukaiyama aldol

Enantioselective synthesis of (2S,3′R,7′Z)-N-(3′-hydroxy-7′-tetradecenoyl)-homoserine lactone
Autor: Gullapalli Kumaraswamy, Neerasa Jayaprakash
Publikováno v: Tetrahedron Letters. 51:6500-6502
A concise enantioselective total synthesis of (2S,3′R,7′Z)-N-(3′-hydroxy-7′-tetradecenoyl)-homoserine lactone is described. Key feature of this protocol is a catalytic asymmetric hydrogenation and a prophenol–zinc-catalyzed diazo addition t

An Organocatalyzed Enantioselective Synthesis of (2S,3R,4S)-4-Hydroxyisoleucine and Its Stereoisomers
Autor: Gullapalli Kumaraswamy, Neerasa Jayaprakash, Balasubramanian Sridhar
Publikováno v: The Journal of Organic Chemistry. 75:2745-2747
A concise enantioselective total synthesis of (2S,3R,4S)-4-hydroxyisoleucine and its stereoisomers is described. A key feature of this protocol is a catalytic enantioselective mannich reaction that is either anti- or syn-selective as genesis of chira

Towards the diastereoselective synthesis of derivative of 11′-epi-brevipolide H
Autor: Neerasa Jayaprakash, Dasa Rambabu, Gullapalli Kumaraswamy, Aniban Ganguly, Rajkumar Banerjee
Publikováno v: Organic & Biomolecular Chemistry. 12:1793
An efficient diastereoselective synthesis of brevipolide H derivative is described. The approach features the use of (i) catalytic asymmetric transfer hydrogenation, (ii) hydroxyl-directed cyclopropanation, and (iii) substrate-controlled catalytic ep
