supporting information, p. 3623 - 3634 (2021/01/09)
The 2,6′-bijuglone natural product diospyrin and its unnatural 3,6′-isomer idospyrin have been synthesized in seven steps each from N,N-diethylsenecioamide in overall yields of 12% and 13%, respectively. The syntheses diverge from ramentaceone (7-methylju
3-Methyl 1,1-bis(trimethylsiloxy) 1,3-butadiene et 4-trimethylsilyl 3-methyl 2-butenoate de trimethylsilyle: preparations et reactions avec le benzaldehyde
Bellassoued, M.,Ennigrou, R.,Gaudemar, M.
, p. 19 - 25 (2007/10/02)
The regioselectivity of the reaction between benzaldehyde and the silylketene acetal prepared from trimethylsilylsenecioate is studied as a function of the catalyst used.CsF leads exclusively to the "branched" product whereas TiCl4 gives the required "lin

Various structural types of nogalamycin congeners and their partial structures, which had been previously synthesized in the course of our synthetic studies on the total syntheses or were originally produced by employing the explored synthetic scheme, were subjected to in vitro cytotoxicity and in vivo antitumor activity assay against P388 murine leukemia.These studies obviously disclosed novel aspects of the structure-activity relationships of nogalamycin congeners.
Halogenated Ketenes. 37. The Synthesis of Pyranones Utilizing the (4 + 2) Cycloaddition of Ketenes and Siloxy Dienes
Brady, William T.,Agho, Michael O.
, p. 501 - 506 (2007/10/02)
The reaction of diphenyl-, dichloro-, and chloroketenes with several siloxy dienes results in (4 + 2) and/or (2 + 2) cycloaddition products depending primarily on substitution in the diene.The (4 + 2) cycloaddition products are easily hydrolyzed to pyranones.These results are discussed in terms of a dipolar intermediate.
