Enantioselective Synthesis of a Furan Lignan (+)-Sylvone
Lee, Eunhye,Bang, Jiyun,Kwon, Jisook,Yu, Chan-Mo
, p. 10359 - 10363 (2015)
A synthesis of natural tetrahydrofuran lignan (+)-sylvone is achieved starting from methyl allenoate in 5 steps. The synthesis begins from an enantioselective aldol reaction of methyl allenoate with 3,4-dimethoxybenzaldehyde to afford α-addition aldol add
An expedient carbon–sulfur bond formation explored through the cellulose sulfonic acid (CSA) catalyzed dithioacetal protection of carbonyl compounds
Kadam, Kailas R.
, p. 530 - 541 (2020/07/03)
A facile carbon–sulfur bond formation was observed through the cellulose sulfonic acid (CSA) catalyzed dithioacetal protection of carbonyl compounds. In a preliminary study, the synthesis and characterization of functionalized bio-polymer, cellulose sulph
Synthesis of 1,3-dithiane and 1,3-dithiolane derivatives by tungstate sulfuric acid: Recyclable and green catalyst
Karami, Bahador,Taei, Mahbubeh,Khodabakhshi, Saeed,Jamshidi, Masih
experimental part, p. 65 - 74 (2012/07/14)
An efficient, novel, and environmentally benign procedure for the thioacetalization of aliphatic and aromatic carbonyl compounds in the presence of catalytic amounts of tungstate sulfuric acid under solvent-free conditions to afford 1,3-dithianes and 1,3-
Silica-PCl5: A novel heterogenous catalyst for simple and efficient chemoselective protection of carbonyl compounds
Pandey, Lokesh Kumar,Pathak, Uma,Tank, Rekha,Mazumder, Avik
experimental part, p. 167 - 171 (2010/07/05)
A simple, efficient and environmentally benign procedure has been developed for chemoselective protection of carbonyl compounds using the newly developed heterogeneous catalyst: Silica-PCl5. A variety of aldehydes and ketones were efficiently c

Sun, Chang-Ming,Lin, Lee-Gin,Yu, Hsi-Jung,Cheng, Chih-Yu,Tsai, Ya-Chuan,Chu, Chi-Wei,Din, Yi-Hui,Chau, Yat-Pang,Don, Ming-Jaw
, p. 1078 - 1081 (2007/10/03)
A series of 4,5-diarylisoxazoles related to combretastatin A-4 (CA-4) were synthesized and evaluated for cytotoxicity against three human cancer cell lines. Among them, compound 6e showed better cytotoxic activity than CA-4 in HeLa and HepG2 cell lines as
Transdithioacetalization of acetals, ketals, oximes, enamines and tosylhydrazones catalysed by natural kaolinitic clay
Jnaneshwara,Barhate,Sudalai,Deshpande,Wakharkar,Gajare,Shingare,Sukumar
, p. 965 - 968 (2007/10/03)
Natural kaolinitic clay efficiently catalyses the transdithioacetalization of acetals, ketals, oximes, enamines and tosylhydrazones with ethane-1,2-dithiol and propane-1,3-dithiol to produce the corresponding dithiolanes in high yields.
An expeditious synthesis of dithioacetals using zeolites
Kumar,Reddy,Singh,Pandey
, p. 67 - 69 (2007/10/02)
A simple and efficient catalytic method for dithioacetalization of various carbonyl compounds (saturated and α,β-unsaturated aliphatic, aromatic, heteroaromatic and hindered) with ethanethiol and 1,3-propanedithiol using H-Y and H-mordenite (H-M) zeolites
ASYMMETRIC TOTAL SYNTHESIS OF NATURAL (-)- AND UNNATURAL (+)-STEGANACIN DETERMINATION OF THE ABSOLUTE CONFIGURATION OF NATURAL ANTITUMOR STEGANACIN
Tomioka, Kiyoshi,Ishiguro, Tsuneo,Iitaka, Yoichi,Koga, Kenji
, p. 1303 - 1312 (2007/10/02)
A virtually complete asymmetric control in the synthesis of 2,3-disubstituted butan-4-olide (10) was demonstrated by employing the butenolide (12) as the chiral acceptor for the conjugate 1,4-addition.Highly efficient asymmetric total synthesis of natural (-)- and unnatural (+)-steganacin was accomplished.The absolute stereostructure of natural antitumor steganacin was determined to be 1.
