A concise synthesis of (4R,5R)-(−)-muricatacin and (4R,5R)-l-(−)-factor from d-glucono-δ-lactone
摘要:
A concise seven-step synthesis of (4R,5R)-(-)-muricatacin and (4R,5R)-L-(-)-factor from inexpensive, commercially available D-glucono-delta-lactone has been accomplished. The keys steps involve a one-pot conversion of the latter to gamma-vinyl-gamma-lactone, cross-metathesis and Wittig olefination. This strategy has potential for the synthesis of analogs by changing the alkyl side chain by Wittig olefination. (C) 2016 Elsevier Ltd. All rights reserved.
