A Carbohydrate-Based Approach for the Total Synthesis of Aculeatin D and 6-epi-Aculeatin D.

[摘要]：A concise approach for the total synthesis of aculeatin D (I) and 6-epi-aculeatin D II employing differentially protected anti,anti-1,3,5-triol alkyne prepd. from a-D-glucoheptonic-g-lactone deriv. is documented. Phenol protecting group manipulation for selective O-debenzylation during the hydrogenation of the diyne intermediate III and one-pot phenolic oxidn. with concomitant spiroketalization highlight the accomplished total synthesis.
