Carbene Transfer Reactions Catalysed by Dyes of the Metalloporphyrin Group.
Carbene transfer reactions are very important transformations in organic synthesis, allowing the generation of structurally challenging products by catalysed cyclopropanation, cyclopropenation, carbene C-H, N-H, O-H, S-H, and Si-H insertion, and olefination of carbonyl compounds. In particular, chiral and achiral metalloporphyrins have been successfully explored as biomimetic catalysts for thes...

متن کاملSynthesis of Phosphorus Derivatives via Multicomponent Reactions
Stable derivatives of oxaphosphaphenanthrenes were prepared using multicomponent reactions of 3-bromo-2-naphthol, dialkyl acetylenedicarboxylate and trimethyl or triphenyl phosphite under microwave conditions with good yields.
متن کاملApplication of Water for Synthesis of Cyclopentadienes via Multi-component Reactions of N-methyl imidazole
A water-accelerated multi-component synthesis of organic target molecules was used as a key method for the preparation of cyclopentadiene derivatives. The three-component condensation reactions of primary amines with alkyl propiolates in the presence of N-methylimidazole in water at room temperature were developed as efficient and clean green synthetic procedures for the high-yielding preparati...
متن کاملGold-Catalyzed Reactions via Cyclopropyl Gold Carbene-like Intermediates
Cycloisomerizations of 1,n-enynes catalyzed by gold(I) proceed via electrophilic species with a highly distorted cyclopropyl gold(I) carbene-like structure, which can react with different nucleophiles to form a wide variety of products by attack at the cyclopropane or the carbene carbons. Particularly important are reactions in which the gold(I) carbene reacts with alkenes to form cyclopropanes...
