โœฆ Synopsis

A previous report from these Laboratories ' described the partial synthesis of gibberellic acid (I) from the trlenic acid Ii and recognized III as an attractive precursor to this key intermediate. IVa, R=CH3 IVb, R=CH2COPhPh V This report demonstrates synthetic methodology for effecting the conversion III-II by a stereo-

A general method for the facile synthesis of ring-A hydroxylated flavones is described. Treatment of the hydroxylated acetophenones 6a-d with enough lithium bls(trimethyl)silyl amide to deprotonate all of the phenols as well as to generate the lithium enolate of the ketone, followed by addition of

The behaviour of gibberellic acid (GA,) under electron impact and chemical ionization conditions has been examined. The tendency of GA, to undergo pyrolysis by the loss of the elements of water and carbon dioxide has been identified. Two methods of sample introduction can be used to minimize the occ
