  Trichosporon beigelli esterase (TBE): a versatile esterase for the resolution of economically important racemates

  摘要：

  A hydrolase producing strain Trichosporon beigelli esterase (TBE) isolated from local cottage cheese in its native form has displayed versatility and high efficacy in the kinetic resolution of a wide range of economically important substrates, which include racemic secondary alcohols, such as 1-(6-methoxy-2-naphtliyl)ethanol (E similar to 316), 1-(3,4-methylenedioxyphenyl)ethanol and pentanol (E similar to 180 and 156 resp.), and alkyl esters of carboxylic acids such as ibuprofen (E similar to 340), 2-(benzylthio)propanoic acid (E similar to 1000). In other substrates such as in the primary alcohol 2-(6-methoxy-2-naphthyl)propan-1-ol and carboxylic acids such as 2-(5-bromo-6-methoxy-2-naphthyl)propanoic acid, 2-(2-naphthyloxy)propanoic acid, and substituted 2-thiopropanoic acids, it displayed moderate to low selectivity. Commercial lipases such as CCL, PPL, and PSL were also used in the resolution of the substrates for comparative studies. (c) 2005 Elsevier Ltd. All rights reserved.

  toluene-α-thiolate, on methyl L-O-ptolysulphonyl-lactate, methyl L-2-chloropropionate, and sodium L-2-chloropropionate, have been used to prepare D-2-acylthio- and D-2-acylthio- and D-2-alkylthio-propionic acids and esters. Extensive racemisation occurs when an excess of thioacetate or thiobenzoate is used; this is attributed to further SN2 displacement, with acetylthio or benzoylthio as a leaving group. Concomitant

  亲核置换反应，由硫代乙酸酯，硫代苯甲酸，甲硫醇和甲苯-α-硫醇盐，上甲基大号- ö - p tolysulphonyl乳酸盐，甲基大号-2-氯丙酸甲酯，和钠大号-2-氯丙酸甲酯，已被用来制备d -2- acylthio-和d -2- acylthio-和d -2-烷硫基-丙酸和酯。当使用过量的硫代乙酸酯或硫代苯甲酸酯时，会发生广泛的消旋作用。这归因于进一步的S N2取代，以乙酰硫基或苯甲酰硫基为离去基团。通过不同的机理，在保留构型的同时也发生了酰基交换。因此，D -2-乙酰基硫代丙酸甲酯与硫代苯甲酸钾产生D -2-苯甲酰基硫代丙酸甲酯。
