One-pot inversion of d -mannono-1,4-lactone for the practical synthesis of l -ribose
摘要:
L-Ribose was synthesized in a concise manner from D-mannono-1,4-lactone using one-pot inversion conditions. Treatment of D-mannono-1,4-lactone with piperidine, followed by mesylation-induced S(N)2-type O-alkylation afforded the desired one-pot inversion in an optimum yield, and the following straightforward transformations provided L-ribose in good yields.
