Total Synthesis of the Proposed Structure of Roxbin B; the Nonidentical Outcome

“…First, intramolecular coupling of 4-O-benzylated digallates on 8 was attempted (Scheme 3). 4, 9 The digallate 8 was prepared through acylation of the 1,2-diol 3 with 3,5-di-O-allyl-4-O-benzylgalloyl chloride (9) followed by deallylation 10 of 10. In the anomeric acylation, use of the Et 3 N induced the β-selectivity.…”
