From the needles of domestic yew, (Taxus baccata), 10-deacetylbaccatin III (10-DAB) can be isolated in quantities of up to 297 mg per kg of fresh needles. Additional quantities of 10-Dcan be obtained from the extract by NaBH4 mediated reductive hydrolysis of baccatin esters. A four-step procedure converts 10-Dinto taxol in 58% overall yield.

Hydrolysis Of

A one-flask, two-step procedure from 3-amino-2-methyl-5,6,7,7a-tetrahydro-1H-pyrrolizin-1-one affords the Streptomyces secondary metabolites legonmycins A and B – three operations overall from methyl N-Boc-prolinate. The key step proceeds in each case via N,O-diacylation, then selective oxidative hydrolysis of the intermediate bicyclic pyrrole and establishes a precedent for the synthesis of related C(7a)-hydroxylated pyrrolizidines.
