摘要:... These were converted to the corresponding iodides which underwent 6- exo - dig radical cyclisation to afford chiral cyclohexanes and carbasugars. Oxidation of the primary alcohols 6a– b gave the corresponding aldehydes which on treatment with Grignard reagents afforded...

摘要:Abstract(#br)Transformation of cyclohexa-1,3- and 1,4-dienes to carbasugars is described. Photooxygenation of dienes gave bicyclic endoperoxides, which were reduced with thiourea to the corresponding 1,4-diols with cis-configuration. Lactonization of the remaining double bond by ...

摘要:Abstract(#br)A series of carbasugars were prepared and their conformational properties studied by means of NMR spectroscopy. The results were compared to those previously found for O-, S-, and C-β-glycoside analogs. While the rotational populations of the hydroxymethyl group ...

摘要:Abstract(#br)Asymmetric total synthesis of (+)-gabosine C, (+)-pericosine B, and (+)-pericosine C has been reported from readily available d -(−)-isoascorbic acid and d -ribose involving Grubbs ring closing metathesis, Morita – Baylis – Hillman (MBH) reaction, and Luche...

摘要:Abstract(#br)Two new polyoxygenated cyclohexenone ‘ketocarbasugars’, named gabosines P and Q ( 1 and 2 ), were isolated from the culture of the actinomycete Streptomycetes strain no. 8, along with two known cyclic dipeptides. The structures and absolute configurations of the...

摘要:... A hydroboration/oxidation sequence was investigated on these 1,1-difluoro-5-methylenecyclopentanes as it would provide fluorinated carbasugars, a new and promising class of glycomimetics. Unfortunately, this reaction was poorly efficient and its regioselectivity not the expec...

摘要:Synthesis of novel polyhydroxylated derivatives of decalin is described. The presented methodology consists in a one-pot copper-catalyzed 1,4-addition of vinylmagnesium bromide to sugar-derived cyclohexenone, followed by an aldol reaction with a derivative of but-3-enal. The obta...

摘要:Abstract(#br)The norbornyl system has been recognized simply as a ‘locked’ carbasugar and a short, general approach to carbasugars and their new siblings, ‘confused’ carbasugars, from readily available 7-ketonorbornanes is reported.
