Prompted by the aim to synthesize for the first time the 7-OH derivatives TRIBOA and DHBOA a general procedure was established in which the crucial lactol unit is obtained by reduction of a lactone precursor (Fig. (10)). [Pg.199]

Finally, the 7-hydroxy substituted aglucones DHBOA and TRIBOA have been prepared [117] by standard hydrogenolyses of 7-benzyloxy precursors over Pd-C in acetic acid. All steps of the reductive pathway proceed with good to excellent yields. This method provides a general access to the 2-hydroxy-2/7-l,4-benzoxazin-3(4/f)-one as well as to the... [Pg.201]
