(±)-N-Isonicotinoyl-2-amino-5-chlorobenzhydrol (1) is a rice plant growth regulator which shortens the second leaf sheaths. One of the enantiomers, (S)-1, was obtained by microbiological asymmetric reduction of 2-amino-5-chlorobenzophenone using Rhodosporidium toruloides followed by isonicotinoylation. Several substituted benzhydrol derivatives were also prepared by use of the same biological method and converted to N-isonicotinoyl compounds. The growth-regulating activities of these compounds were evaluated.
(±)-N-异烟酰基-2-氨基-5-氯苯基醇 (1) 是一种水稻植物生长调节剂,可缩短第二片叶鞘。通过使用红酵母Rhodosporidium toruloides对2-氨基-5-氯苯酮进行微生物不对称还原,得到了其中一个对映体(S)-1,随后进行异烟酰化。还通过相同的生物方法制备了几种取代的苯基醇衍生物,并转化为N-异烟酰基化合物。对这些化合物的生长调节活性进行了评估。
