Organoboron compounds in new synthetic reactions
A general and convenient method for the stereoand regiospecific synthesis of conjugated alkadienes, alkenynes, arylated alkenes, and other olefinic compounds is described. The reaction of (E)or (Z)-lalkenyldisiamylboranes, or 2-(E)-l-alkenyl-l ,3,2-benzodioxaboroles easily obtainable by hydroboration, with either (E)or (Z)-l-alkenyl halides in the presence of a catalytic amount of tetrakis(trip...
متن کاملAsymmetric tandem reactions: New synthetic strategies*
The use of domino and multicomponent reactions in asymmetric synthesis is constantly increasing nowadays. This allows for the synthesis of complex molecules in a single synthetic sequence, usually with high atom economy. Herein, we report three examples of new asymmetric tandem reactions recently developed in our laboratories, giving rise to new families of enantiomerically enriched fluorinated...
متن کاملProtease-Catalyzed Synthetic Reactions in Ionic Liquids
Enzymes are very effective and biodegradable catalysts, and act under mild conditions such as room temperature, atmospheric pressure, and around pH 7. Consequently, the applications of enzymes to the organic synthesis have extensively been studied from the standpoint of the development of sustainable synthetic processes (Truesdell, 2005). Enzymes exhibit the high activity and specificity not on...
متن کاملSynthetic autocatalysts show organocatalysis of other reactions.
A molecule capable of both autocatalysis and organocatalysis was synthesized. The autocatalytic activity results from the self-complementary recognition sites provided by hydrogen bonding between heterocyclic subunits and the organocatalysis resides in an embedded thiourea function. The behavior of the molecule suggests both replication and metabolism can be engineered into synthetic compounds.
متن کاملHalf-Century Journey from Synthetic Organic Chemistry to Mathematical Stereochemistry through Chemoinformatics
My half-century journey started from synthetic organic chemistry. During the first stage of my journey, my interest in stereochemistry was initiated through the investigation on the participation of steric effects in reactive intermediates, cylophanes, strained heterocycles, and organic compounds for photography. In chemoinformatics as the next stage of the journey, I proposed the concept of im...
