Novel Asymmetrical Dianionic Polyimido-Sulfur(IV)-Ylides
Sulfurdiimides RN=S=NR react in donating solvents with two equivalents of lithiumalkyls to give the dimeric C,N-dilithium-methylenediimidosulfite solvent adducts [(Et2O)Li2{H2CS(NSiMe3)(NBu)}]2 (1) and [(thf)Li2{H8C4S(NBu)2}]2 (2). Firstly, addition of a lithiumalkyl to sulfurdiimide gives the diimidosulfinates [RS(NR )2] (1: R = Me, R = tBu, SiMe3; 2: R = nBu; R = tBu) while in a second step t...
متن کاملA novel synthesis of diastereomerically pure spiro- oxindolopyrrolizidines and oxindolopyrrolidines via cycloaddition reactions of azomethine ylides
An efficient one-pot three-component procedure for the synthesis of new chiral spiro oxindolopyrrolidines/pyrrolizidines with highly regio- and diastereo-enantio, selective from 1,3-dipolar cycloaddition of azomethine ylides and chiral menthol-drived trans-cinnamic are described. The mechanism of the reaction is discussed on basis of the assignment of the absolute configuration of one of the cy...
متن کاملBifunctional AgOAc-catalyzed asymmetric [3 + 2] cycloaddition of azomethine ylides.
[reaction: see text] A bifunctional AgOAc-catalyzed asymmetric cycloaddition of azomethine ylides with electronic-deficient alkenes was developed using ferrocenyloxazoline-derived N,P ligands. The reactive metal-bound azomethine ylide dipole is formed by the deprotonation with acetate, and extra base is not necessary. The reactions proceed with high enantioselectivity. This method provides an e...
متن کاملOrganocatalytic enantioselective (3+2) cycloaddition using stable azomethine ylides.
We have developed a highly efficient procedure for carrying out the catalytic enantioselective (3+2) cycloaddition between enals and stable azomethine ylides such as isoquinolinium and phthalizinium methylides. Under the optimized reaction conditions highly substituted chiral pyrroloisoquinolines and pyrrolophthalazines have been obtained in high yields and excellent diastereo- and enantioselec...
متن کاملThe continuous-flow cycloaddition of azomethine ylides to carbon nanotubes.
This communication demonstrates a straightforward continuous-flow method for efficient exohedral functionalisation of carbon nanotubes which affords soluble samples in a much shorter time over conventional batch processing.
