title: Microbial and reducing agents catalyze the rearrangement of taxanes.
abstract: 5alpha, 7beta, 9alpha, 10beta, 13alpha-Pentahydroxy-4(20),11(12)-taxadiene derivative 1 was converted to two unprecedented 1(15-->11)abeo-taxanes and a taxane derivative with a C10-C11 double bond by Absidia coerula ATCC 10738a. A similar compound was obtained from treatment with zinc of a triacetoxy-4(20),11(12)-taxadiene derivative.
