摘要：
The sodium borohydride reduction of coumarin to the corresponding alkanol and alkenol has been investigated in the presence and absence of beta-cyclodextrin (beta-CD). Excellent selectivity is observed when beta-CD-coumarin complex is reduced in solid state at 0 degrees C and the alkenol, cis-o-hydroxycinnamyl alcohol is the major product. Complex formation and the mode of substrate insertion into the CD cavity have been analysed using various physical methods.
