Production of the large cyclic ketone which utilizes the addition to the alkene of ketone(57)< Abstract > As for this invention, being production method of the large cyclic ketone due to the reaction sequence, one process, formula of ketone (1) (in formula, R =H or low-grade alkyl, R...
The invention is a generalized hydroacylation reaction. The reaction involves the activation of a selected aldehyde by converting by iminization to an aldimine or an aminal. The imine group replaces the carbonyl group. The imine C-H bond is then susceptible to attack by a chosen olefin, and ...
Carbonnucleophiles(pKa≥20), such as ketone enolates, sometimes attack the central carbon of a preformed η3-allyl complex to produce acyclopropane. This mode of attack is observed in the reaction of the lithium enolate of 2,4-dimethyl-3-pentanone with an η3-allylpalladium chloride–TMEDA com...
A series of useful functional groups, such as bromine (6), reactive carbonyl groups (13–16), a terminal alkene (18), an internal alkyne (19) and an acetal (21) tolerate the reaction conditions well. Some of these functional groups have difficulty surviving the conventional Weinreb ketone ...
