โœฆ Synopsis

The biosynthetically important C-20 gibberellin, gibberellin A prepared from the readily obtained C-19 gibberellin, gibberelll acid 8, by means of 1% 5, has been an efficient stereocontrolled ten step sequence. Cibberellin A,g 5 (IGA,~)' has been strongly implicated as a key intermediate in the postulated "early 13-hydroxylation" biosynthetic pathway between the C-20 gibberellin, GA 12 1. and the C-19 gibberellin, GA, 7, in several higher plants, 2 1.e 1 -t 3 + 4 + 5 + 6 + + 7.

Total synthesis of (\*t\_)-gibberellic acid was accomplished via highly stereocontrolled route. A number of synthetic efforts for Cl9 -gibberellin phytohormones have been made in recent years.

Endogenous gibberellins (GAs) were extracted from safflower (Carthamus tinctorius L .) stems and detected by capillary gas chromatography-mass spectrometry from which GA,, GA 3 , GA ' ,, GA,,, GA,,, and probably, GA" were detected . The detection of these GAs suggests that the early 13-OH biosynthet
