Total synthesis of aculeatins A and B from d-glucose
摘要:
A simple and highly efficient total synthesis of cytotoxic dioxa-dispiroketals aculeatins A and B is disclosed. The key steps include alkynylation of a chiral aldehyde and in situ deprotection, spirocyclization of a 3,5-acetonide protected ketone. (C) 2008 Elsevier Ltd. All rights reserved.
