Synthetic approaches to the tricarbonyl subunit of rapamycin

Creator:: LaMunyon, James B.
Abstract:: Rapamycin (5) was isolated in 1975 from the soil bacteria Streptomyces hygroscopicus and its structure was determined from spectroscopic techniques and an x-ray crystallographic analysis. Although it was initially found to exhibit antibiotic activity, it was subsequently shown to possess potent immunosuppressive activity as well. Three approaches to the synthesis...
