Synthesis of Optically Active Organoantimony Compounds Having an (S)-.ALPHA.-Methylbenzyldimethylamine Group and Its Evaluation for Asymmetric Reaction.

Abstract: The chemistry of asymmetric catalysts is an interesting research field in asymmetric reactions and has recently been the focus of attention.1) A number of chiral ligands containing nitrogen, 2) phosphorus [3][4][5][6][7][8][9] and arsenic [10][11][12][13] have been widely studied and are well documented. With respect to enantiomerically pure phosphine ligands bearing a chiral benzylamine moiety, (R/S)-[a-methyl-2-(diphenylphosphino)-benzyl]dimethylamine (AMPhos) [14][15][16][17] and its (h 6 -arene)-chromium c… Show more

“…[1][2][3] In particular, trivalent organoantimony(III) compounds (stibanes) have been used for a wide variety of transformations such as alkylation of carbonyl compounds, 4) Pd-catalyzed cross-coupling reactions, [5][6][7][8][9][10][11] photochemical reaction, 12) catalytic oxidative cyclization, 13) and asymmetric reactions with optically active compounds. [14][15][16][17][18] Stibane reagents such as triphenylstibane have low toxicity, [19][20][21] and are therefore promising reagents in organic synthesis. Extensive studies have been carried out on the reductive dehalogenation reactions of α-halocarbonyl compounds using reagents such as active metals, low-valent metals, metal hydrides, and halide salts.…”

“…[1][2][3][4][5] As for the application of trivalent organoantimony compounds (stibanes), a wide variety of reactions such as self-coupling reactions, 6,7) cross-coupling reactions, [8][9][10][11][12][13] photoreaction, 14) and asymmetric reactions with optically active organoantimony compounds [15][16][17][18][19] have been reported during the last two decades. On the other hand, the conversion of benzoin into benzil has been accomplished by oxidation with a variety of reagents; i.e., bismuthane oxide, 20) bismuthane imides, 21) alumina-supported copper sulfate under microwave irradiation, 22) and the Burgess reagent, 23) and by transition metal-catalyzed oxidation with bismuth nitrate-copper acetate, 24) aerobic oxygen, 25,26) diacetoxyiodobenzene, 27) and allyl diethyl phosphate.…”
