R. Nakashima et al., STEREOCHEMISTRY AND BIOLOGICAL-ACTIVITY OF METHYL HYDROGEN 3-PHENYL-2,2'-IMINODIPRO-PIONATE PRODUCED BY BOTRYTIS-SQUAMOSA, Bioscience, biotechnology, and biochemistry, 57(9), 1993, pp. 1514-1517
The stereochemistry of 1-methyl hydrogen 3-phenyl-2,2'-iminodipropiona
te (BSF-A, 1) was determined to be 2S, 2'S by comparing the spectral d
ata of 1 with those of synthetic derivatives. The effects of BSF-A (1)
and its analogs on the growth rate of lettuce seedlings were examined
. Both diastereomers, 3a (2S, 2'S) and 3b (2S, 2'R), of dimethyl 3-phe
nyl-2,2'-iminodipropionate and a regioisomer, 1'-methyl hydrogen 3-phe
nyl-2,2'-iminodipropionate (2), exhibited biological activity similar
to that of natural product BSF-A (1).
