New approach to carbamoyl-polyoxamic acid derivatives through an oxazolidinone synthon
摘要:
A key oxazolidinone synthon was obtained through condensation of vinyl magnesium with an epoxyimine, followed by a carbonation/cyclisation reaction in the presence of ammonium carbonate. Oxidative ozonolysis after protection and carbamolylation (optional) afforded the (5-0-carbamoyl-)polyoxamic derivatives in 9% (or 14%) total yield in six (or four) steps. (c) 2007 Elsevier Ltd.
