Wu, Wen-Biao; Mu, Bo-Shuai; Yu, Jin-Sheng; Zhou, Jian published the artcile< Me2(CH2 = CH)SiCN: a bifunctional ethylene equivalent for Diels-Alder reaction based controllable tandem synthesis>, Electric Literature of 3893-18-3, the main research area is cyclohexenyl ketone perpn crystal structure mol; cyclohexancarbonitrile derivative perpn crystal structure mol; ylide aldehyde tandem reaction bifunctional silyl reagent.
A bifunctional silyl reagent Me2(CH2=CH)SiCN was developed as a novel ethylene equivalent for the Diels-Alder (DA) reaction. The use of this reagent enabled the controllable synthesis of value-added cyclohexenyl ketones I [R = Ph, 4-MeC6H4, 3-FC6H4, etc.; R1 = Me, Et, Ph, etc.], II [R2 = H, 7-OMe, 6-Br; X = CH2, O] or 2-acyl cyclohexancarbonitrile derivatives III [R3 = Me, cyclopropyl, iPr, Ph; R4 = Ph, 4-MeC6H4, 4-FC6H4, etc.] through a five- or six-step tandem sequence based on a Wittig/cyanosilylation/DA reaction/retro-cyanosilylation/isomerization of P-ylides and enals that involved a temporary silicon-tethered intramol. DA reaction.
Chemical Science published new progress about Crystal structure. 3893-18-3 belongs to class bromides-buliding-blocks, and the molecular formula is C9H7BrO, Electric Literature of 3893-18-3.
