P. Gupta et al., BOROHYDRIDE REDUCTION OF 3-SUBSTITUTED PHENYLMETHYLFURAN-2-ONES - AN INTERESTING EXAMPLE OF CHEMOSELECTIVE REACTIONS, Indian journal of chemistry. Sect. B: organic chemistry, including medical chemistry, 33(9), 1994, pp. 825-828
The reaction of ethyl H)-oxofuran-3-yl)methyl]phenoxyacetate/propionat
e/ butyrate (7, 8 and 9) with sodium borohydride has been studied. Com
pound 7 exhibits chemoselectivity towards the reduction of ester group
and compound 9 exhibits chemoselectivity towards the lactone ring ope
ning. Compound 8, however, does not exhibit any such chemoselectivity.
