Publication Metadata only Eliminative deoxygenation of substituted-α-halosulfoxides(1983-01-01) Vichai Reutrakul; Patcharin Poochaivatanon; Mahidol UniversityThe reaction of substituted-halosulfoxides with TiCl4-Zn in ether gave the corresponding phenyl vinyl sulfides in good yields. © 1983.Publication Metadata only The synthesis of α, β-unsaturated aldehydes by one-carbon homologation of carbonyl compounds(1977-01-01) Vichai Reutrakul; Wipa Kanghae; Mahidol UniversityPublication Metadata only Pyrolysis of β-hydroxy-α-chlorosulfoxide: A simple synthesis of chloromethylketones(1977-01-01) Vichai Reutrakul; Wipa Kanghae; Mahidol UniversityPublication Metadata only Phenylbutanoids from Zingiber cassumunar(1981-01-01) Pittaya Tuntiwachwuttikul; Orasa Pancharoen; Thaworn Jaipetch; Vichai Reutrakul; Thailand Ministry of Public Health; Mahidol UniversityFive novel phenylbutanoids have been isolated from the rhizomes of Zingiber cassumunar. 3,4-Dimethoxybenzaldehyde 2,4,5-trimethoxy-benzaldehyde are also reported from the same source. © 1981.Publication Metadata only Fluoromethyl phenyl sulfoxide: Highly convenient syntheses of vinyl fluorides and fluoromethylketones(1983-01-01) Vichai Reutrakul; Vatcharin Rukachaisirikul; Mahidol UniversityAlkylation of lithio fluoromethyl phenyl sulfoxide 2 gave the alkylated products in high yields. Pyrolysis of the products led to vinyl fluorides in excellent yields. The reaction of 2 with carbonyl compounds led to the corresponding β-hydroxy-α-fluoromethyl phenyl sulfoxides. Pyrolysis of some of the sulfoxides gave fluoromethylketones in moderate yields. © 1983.Publication Metadata only An improved procedure for the synthesis of fluoromethylketones: Flash vacuum pyrolytic elimination(1994-07-04) Vichai Reutrakul; Thongchai Kruahong; Manat Pohmaktor; Mahidol UniversityFluoromethylketones 3 are synthesized in good yields by a flash vacuum pyrolytic elimination of 2. Studies on the improved synthesis of 2 leads to the evidence on the existence of α,α-dilithio fluoromethyl phenyl sulfoxide. © 1994.Publication Metadata only A highly convenient procedure for the hydrolysis of terminal phenyl vinyl sulfides(1983-01-01) Vichai Reutrakul; Patcharin Poochaivatananon; Mahidol UniversityTerminal vinyl and chlorovinyl sulfides are hydrolyzed by 70% perchloric acid-thiophenol in benzene to the corresponding diphenyl thioacetals and thioesters in good yields. © 1983.Publication Metadata only Iodomethyl phenyl sulfoxide: reactivity and synthetic applications(1984-01-01) Vichai Reutrakul; Chitchanun Panyachotipun; Viwat Hahnvajanawong; S. Sotheeswaran; Mahidol University; University of PeradeniyaLithio iodomethyl phenyl sulfoxides reacted with alkyl halides and carbonyl compounds to give adducts in good to moderate yields. Solvolysis of the carbonyl adducts led to sulfones or the ring expanded product. © 1984.Publication Metadata only Asymmetric total synthesis of (+)-swainsonine(2011-01-21) Soontorn Chooprayoon; Chutima Kuhakarn; Patoomratana Tuchinda; Vichai Reutrakul; Manat Pohmakotr; Mahidol UniversityA concise asymmetric synthesis of (+)-swainsonine (ent-1) is described starting from 2, which was readily prepared from commercially available l-glutamic acid. The method features installation of the indolizidine ring via an intramolecular cyclisation of α-sulfinyl carbanion as a key step. (+)-Swainsonine was obtained in 11.8% overall yield in 10 steps. © 2011 The Royal Society of Chemistry.Publication Metadata only Asymmetric synthesis of furofurans(2017-12-20) Manat Pohmakotr; Chutima Kuhakarn; Vichai Reutrakul; Darunee Soorukram; Mahidol University© 2017 Elsevier Ltd Furofurans are one of the largest sub-types of classical lignans which have been found to possess a broad range of important biological activities. Tremendous efforts have been directed to develop synthetic methodologies for the synthesis of furofurans, especially in a stereoselective manner, due to their interesting bioactivities associated with the structural and stereochemical complexity. This article summarizes the reports on asymmetric synthesis of furofurans disclosed during the period of 2004–2017.
