Investigation of the Passerini and Ugi reactions in β-lactam aldehydes. Synthetic applications.
Passerini (P-3CR) and Ugi (U-4CR) reactions were investigated in 4-oxoazetidine-2-carboxaldehydes, affording the corresponding Passerini and Ugi adducts with moderate diastereoselectivity in high yields. Fortunately, the obtained mixtures of isomers syn/anti were separated in most cases. The scope of both IMCRs has been studied using a variety of isocyanides, carboxylic acids and amines. Ugi ad...
متن کاملEfficient construction of a 3C-xanthone-linked 3C-chromone scaffold by novel double Michael additions and cyclizations.
A novel base-promoted cascade reaction of 2-methyl-3-(1-alkynyl)chromones to produce a 3C-xanthone-linked 3C-chromone scaffold has been developed. This tandem process involves multiple reactions such as Michael additions/cyclizations under mild conditions without a transition metal catalyst and inert atmosphere.
متن کاملDomino reactions of 2-methyl chromones containing an electron withdrawing group with chromone-fused dienes.
Domino reactions of 2-methyl substituted chromones containing an electron withdrawing group at the 3-position with chromone-fused dienes synthesized a diverse range of benzo[a]xanthones and complicated chromone derivatives. These multiple-step reactions result in either two or three new C-C bonds without a transition metal catalyst or an inert atmosphere.
متن کاملSilver-catalyzed cascade reaction of tosylmethyl isocyanide (TosMIC) with propargylic alcohols to (E)-vinyl sulfones: dual roles of TosMIC.
An unprecedented silver-catalyzed cascade reaction of tosylmethyl isocyanide (TosMIC) with propargylic alcohols for the efficient synthesis of (E)-vinyl sulfones has been developed where TosMIC plays a dual role as both the reactant in the allenylation of propargylic alcohols and the sulfonyl source.
متن کاملA temporary stereocentre approach for the asymmetric synthesis of chiral cyclopropane-carboxaldehydes.
A novel way of combining chiral auxiliaries and substrate directable reactions is described that employs a three-step sequence of aldol/cyclopropanation/retro-aldol reactions for the asymmetric synthesis of enantiopure cyclopropane-carboxaldehydes. In the first step, reaction of the boron enolate of (S)-N-propionyl-5,5-dimethyl-oxazolidin-2-one with a series of alpha,beta-unsaturated aldehydes ...
