Total Synthesis of (+)-Prelaureatin and (+)-Laurallene
摘要:
The first total syntheses of (+)-prelaureatin and (+)-laurallene are described. An asymmetric glycolate aldol addition was followed by a ring-closing metathesis to close the eight-membered ring allowing construction of the oxocene core of (+)-prelaureatin and (+)-laurallene in seven synthetic steps from (R)-benzylglycidyl ether.
