Manganese(III)-mediated alkenyl C(sp2)-P bond formation from the reaction of β-nitrostyrenes with dialkyl phosphites.
Mn(OAc)3-mediated tandem phosphonyl radical addition to β-nitrostyrenes followed by denitration to form (E)-2-alkenyl phosphonates in good yield is described.
متن کاملPd-catalyzed P-arylation of triarylantimony dicarboxylates with dialkyl H-phosphites without a base: synthesis of arylphosphonates.
The reaction of triarylantimony diacetates [Ar3Sb(OAc)2] with dialkyl H-phosphites [H-PO(OR)2] in the presence of a Pd(PPh3)4 (5 mol%) catalyst led to the formation of arylphosphonates in moderate to excellent yield under base-free conditions. This reaction is the first example of carbon-phosphorus bond formation by using an organoantimony compound as a pseudo-halide.
متن کاملPromoted Preparation of Aminophosphonate and Functionalized Coumarins Derivatives as Key Constituent of Many Pharmaceutical Compounds
The reaction between trialkyl phosphites with dialkyl actylenedicarboxylates in the presence of 2-hydroxyquinoline (2-quinolinol) leads to β-aminophsphonates derivatives which they have many applications in medicinal chemistry. When the reaction was performed by triphenylphosphite, a new pyrano quinoline compounds were obtained in fairly good yields. These compounds also ...
متن کاملReaction of dialkyl carbonates with alcohols: Defining a scale of the best leaving and entering groups*
A series of dialkyl and methyl alkyl carbonates has been synthesized and their reactivity investigated. The behavior of preferential leaving and entering groups for the newly synthesized carbonates has been accurately investigated. Both experimental and computational studies agreed that the scale of leaving groups follows the trend: PhCH2O –, MeO– ≥ EtO–, CH3(CH2)2O –, CH3(CH2)7O – > (CH3)2CHO ...
متن کاملRadical deoxygenation of hydroxyl groups via phosphites.
A highly efficient, two-step sequence method for the deoxygenation of hydroxyl groups has been developed. The method involves the preparation of the 2-(2-iodophenyl)ethyl methyl phosphite derivative of an alcohol using methyl dichlorophosphite and 2-(2-iodophenyl)ethanol. Treatment of the phosphite intermediate with (n-Bu)3SnH/AIBN in refluxing benzene cleanly produces the deoxygenation product...
