In this work, tetra butyl ammonium hydroxide ([Bu4N]OH) and magnetic nano particles (Fe3O4@SiO2@CH2)3NH2) were introduced as efficient catalysts for the regioselective ring openi

Enantiomerically pure (S)-tributylstannyl[D1]methanol and (R)- and (S)-tributylstannyl[D1]methyl benzoates were Stille-coupled with bromobenzene and benzoyl chloride in 1,4-dioxane and toluene using [(Ph 3P)4Pd] or [(Ph3P)2PdCl2] either alone or in combination with CuCN as cocatalyst at temperatures up to 80 °C. The products were found to be enantiomerically pure. (R)- and (S)-N-(tributylstannyl[D1]methyl)phthalimides gave enantiomerically pure products with benzoyl chloride, but with bromobenzene protected phenyl[D1]methylamines gave products of only 52-69 % ee depending on the solvent used. Tributyl(thio[D1]methyl)stannanes could not be Stille-coupled with benzoyl chloride or with bromobenzene. Similarly, dimethyl phenyl[D1]methylboronate underwent a Suzuki-Miyaura coupling with bromobenzene to give phenyl[D1]methylsilane with 99 % ee. All couplings followed a retentive course and, except in one case, the intermediate [XCHDPdLn] complexes were found to be microscopically configurationally stable. Stille coupling of enantiomerically pure tributylstannyl[D1]methanol, its benzoate, and the N-(tributylstannyl[D1]methyl)phthalimide with bromobenzene and benzoyl chloride furnished products containing a chiral XCHD group. Overall net retention of configuration was found in all cases.

An efficient three-step methodology developed for the preparation of 1,2-amino alcohols. In the first step a rapid coupling between bromoketones and potassium phthalimide in ionic liquid produced-phthalimido ketones in quantitative yields, which is followed by a facile reduction using NaCNBH 3 in acetic acid to give corresponding phthalimido alcohols and finally effecting hydrazinolysis in water at 60C to yield biologically important 1,2-amino alcohols.

The expedient synthesis of enantiopure masked 1,2-amino alcohols (ee >99%) including their alkyl substituted analogues has been achieved by the regioselective ring opening of epoxides using phthalimide, followed by highly efficient kinetic resolution under mild and environmentally friendly conditions. The addition of co-solvents during kinetic resolution significantly improved the enantioselectivity with reduction in time.

, p. 4747 - 4751 (2007/10/03)
Efficient assembly of substituted oxazolo-, oxazino-, and oxazepinoisoindolinones (5-7, 12-15 and 19) is described in three steps according to an acidic α-oxoamidoalkylation reaction from ready available phthalic anhydride by successive imidation, sodium borohydride reduction and intramolecular cationic cyclization involving N-acyliminium species. The relative stereochemistry accompanying these reactions was also discussed.

A mixture of tin(II) triflate/pybox and polymethylhydrosiloxane (PMHS) in methanol effects the efficient reduction of ketones; the use of an enantiomerically pure pybox ligand leads to moderate enantioselectivity. (C) 2000 Elsevier Science Ltd.

α-Halogenoalkyl carboxylates (FG-R1CH(X)(OCOR2); FG = COOR, CN, SR; X = I, Br) were readily prepared by the addition of an acid chloride or bromide (R2COX; X = Br or Cl) to an aldehyde (FG-RCHO) in the presence of a catalytic amount of ZnCl2.They insert efficiently zinc dust in THF-DMSO (X = Br, 8 - 10 deg C, 6 - 10 h) affording the corresponding zinc organometallics at the α position to oxygen FG-RCH(ZnBr)(OAc).After the addition of the THF-soluble copper salt CuCN*2LiCl, the corresponding copper reagents FG-RCH(Cu(CN)ZnBr)(OAc) are formed and reacted with variousclasses of electrophiles such as acid chlorides, aldehydes, enones, allylic and alkynyl halides, activated alkynes, nitro olefins and alkylidenemalonates providing polyfunctional molecules in excellent yields.Similarly, zinc organometallics at the α position to the nitrogen of cyclic imides were prepared by the zinc insertion to cyclic α-chloromethyl (or α-chloroethyl) imides.After their transmetalation to the corresponding copper organometallic ((R1CO)2NCH(R)(Cu(CN)ZnCl); R = Me or H), they were reacted with allylic and alkynyl halides and ethyl propiolate affording polyfunctional imides.The reaction of cyclic N-(chloromethyl)imides with aldehydes in the presence of chromium(II) chloride in THF furnishes protected amino alcohols in 36 - 95percent yield.

Fluoride-induced desilylation of (α-phthalimido-, α-morpholino-, and α-acetamidobenzyl)silanes and a (phthalimidomethyl)silane generates the corresponding α-amino carbanions which add to a variety of aldehydes.The conversion of phthalimido group of the adducts into amino moiety leads to β-amino alcohols.This simple reaction sequence offers a new and general method of nucleophilic aminomethylation.
