PROCEDURE

实验过程

Starting from 10.4 g (50 mmol) of 4,5-epoxy-7-nitro-2,3,4,5-tetrahydro-1-benzoxepin, 6.7 g of trans-7-nitro-5-(5-(R,S)-methyl-2-oxo-pyrrolidin-1-yl)-4-trimethylsilyloxy-2,3,4,5-tetrahydro-1-benzoxepin melting in the range 179°-185° C. are isolated. After elimination of the silyl group and after crystallization and chromatography on silica gel (ethyl acetate/cyclohexane 7:3) the diastereomers A and B are obtained.
