エチル−4−t−ブチロキシカルボニルアミノ−2−オキソ−3−ブテナート200mg(0.8mmol)、Ru(p−cymene)[(R,R)−Tsdpen]4mg,ギ酸−トリエチルアミン共沸混合物2mL及びテトラヒドロフラン(THF)2mLを混合した溶液を30℃で撹拌反応させた。16時間後、GCで原料の消失を確認した後、溶媒を留去して目的のエチル−4−t−ブチロキシカルボニルアミノ−2−(R)−ヒドロキシブチレート171mg(MW:247.29,0.69mmol)を得た。収率:87%、光学純度:66.1%ee。1H−NMRデータは、実施例1の1H−NMRデータと一致した。
エチル−4−t−ブチロキシカルボニルアミノ−2−オキソ−3−ブテナート250mg、下記表7に示す触媒を該エチル−4−t−ブチロキシカルボニルアミノ−2−オキソ−3−ブテナートに対して1/100mol及び同表7に示す溶媒1.5mLを混合した溶液を80℃、水素圧3MPaで7時間不斉水素化反応を行った。GCで原料の消失を確認した後、溶媒を留去し、目的のエチル−4−t−ブチロキシカルボニルアミノ−2−ヒドロキシブチレートを得た。結果を表7に示す。
実施例1と同様の方法で得られた光学純度79.2%eeのエチル−4−t−ブチロキシカルボニルアミノ−2−(R)−ヒドロキシブチレート3gを下記表8に示す溶媒A及び溶媒Bとの混合溶液を用いて、下記表8に示す条件で晶析を行って、目的のエチル−4−t−ブチロキシカルボニルアミノ−2−(R)−ヒロドキシブチレートを得た。結果を表8に示す。
