実験手順

A suspension of 0.35 g of the above 83:17 mixture of the two 1:1 mixtures of the (2R,4S) and (2S,4S) and respectively (2R,4R) and (2S,4R) isomers of 2-[(S)-1-[2-oxo-1,3,2-dioxathiolan-4-yl]-2-phenylethyl]-2,3-dihydro-1H-isoindol-1,3-dione, 0.24 g of N-tert.butyl-decahydro-(4aS,8aS)-isoquinoline-3(S)-carboxamide and 0.21 g of sodium carbonate in 3.5 ml of isobutyl methyl ketone is heated to reflux for 24 hours, thereafter cooled and filtered. The filtrate is purified on silica gel with hexane/ethyl acetate (4:1). After evaporation and drying there is obtained 0.34 g (65%) of pure N-tert.butyl-decahydro-2-[2(R)-hydroxy-4-phenyl-3(S)-phthalimidobutyl]-(4aS,8aS)-isoquinoline-3(S)-carboxamide, IR (KBr): 3388m (OH), 1771m and 1708s (C=O of imide).
