  Synthesis and Reactivity of N-[Bis(trimethylsilyl)methyl]heterocumulenes

  摘要：

  A number of N-heterocumulenes bearing the (Me(3)Si)(2)CH (BSM) substituent adjacent to the terminal nitrogen atom of the heterocumulene function, namely BSM-N=C=O (2), BSM-N=C=S (3), BSM-N=C=NR(4: R = BSM; 5: R = C6H5), BSM-N=C=CR(1)R(2) (9a: R(1) = R(2) = C6H5; 9b: R(1) = H, R(2) = SiMe(3); 10: R(1) = R(2) = CH3; 12: R(1) = H; R(2) = CH3), and BSM-N=S=O (14), have been synthesized. The synthetic utility of the BSM-N-substituted heterocumulenes has been explored through the creation of a carbanion center at the a position relative to nitrogen. In particular, the following reactions have been studied: (i) the nucleophilic addition of MeLi to compounds 2 and 5, (ii) the MeLi-induced deprotonation of ketene imines 9a,b (this investigation includes the study of the regiochemical output of the addition of electrophiles (H2O, Mel, Me(2)CHI) to the resulting 1,3-dipoles; and (iii) the TBAF-induced desilylation of compounds 2 and 9a followed by reaction with benzaldehyde.

  thermal [3 + 2] cycloaddition reactions with azides roughly 50- to 100-fold faster than comparable noncharged alkynes. Further, the reaction is highly 1,4-regioselective (dr up to 99:1) owing to the selective stabilization of 1,4-TS transition states via conjugative π-acceptor assistance of the alkyne triazolium ring. The novel cationic triazolium alkynes also accelerate the CuAAC reaction to provide bis(1

  4-炔基-1,2,3-三唑鎓阳离子经历热[3 + 2]环加成反应，叠氮化物的速度比不带电的炔烃快50到100倍。此外，由于经由炔三唑环的共轭π-受体辅助的1,4-TS过渡态的选择性稳定，该反应是高度1,4-区域选择性的（dr高达99：1）。新型阳离子三唑鎓炔烃还可以加速CuAAC反应，以“超快”方式（<5分钟）提供双（1,2,3-三唑）。

  A straightforward general access to diversely substituted acyclic or cyclic enamides and dienamides is accomplished by using a fluoride induced Peterson olefination of carbonyl compounds and enolizable amides derived from C,C-bis(trimethylsilyl) methylamine.
