  Synthesis of all of the stereoisomers of β3-adrenoceptor antagonist SR 59230 based on the spontaneous resolution of 3-(2-ethylphenoxy)propane-1,2-diol

  摘要：

  Racemic 3-(2-ethylphenoxy)propane-1,2-diol 2 has been effectively resolved into (S)- and (R)-enantiomers by a preferential crystallization procedure. Non-racemic diols 2, obtained via a Mitsunobu reaction, have been converted into the non-racemic 1,2-epoxy-3-(2-ethylphenoxy)propanes (S)- and (R)-5 and then into non-racemic 3-(2-ethylphenoxy)-1(1,2,3,4-tetrahydronaphth-1-ylamino)-2-propanols 1. The characteristics of all four stereoisomers, (S,S)-1 (SR 59230), (R,R)-1 (SR 59483), (R,S)-1 and (S,R)-1 (SR 59231) and their hydrogen oxalates with a 1:1 composition have been presented. The crystalline oxalates (S,S)-1 center dot C2H2O4 (SR 59230A) and (R,S)-1 center dot 0.5C(2)H(2)O(4) were studied by single crystal X-ray diffraction. (C) 2016 Elsevier Ltd. All rights reserved.

  derived and binary phase diagrams were reconstructed for the whole family. Solid racemic compounds stabilities were ranked for the four substances. Spontaneous resolution was established for the registered chiral drug mephenesin and its ethyl analogue. Metastable anomalous conglomerate, forming crystals having three independent R* and one independent S* molecules in the unit cell, is formed during solution

  the enzyme active pocket has led to a smart library of epoxide hydrolase variants with an expanded substrate spectrum covering a series of typical β‐blocker precursors. Improved activities of 6‐ to 430‐fold were achieved by redesigning the active site at two predicted hot spots. This study represents a breakthrough in protein engineering of epoxide hydrolases and resulted in enhanced activity toward
