A new process for resolution of an enantiomeric mixture of C3-hydroxyl substituted β-lactams is disclosed. Generally, the enantiomeric mixture is treated with an optically active proline acylating agent to form a C3-ester substituted β-lactam diastereomer or a mixture of C3-ester substituted β-lactam diastereomers followed by selective recovery of the unreacted enantiomer or of one of the diastereomers.

The present invention provides processes for the production of polycyclic fused ring compounds. The polycyclic fused ring compounds are produced by protecting a polycyclic fused ring polyol with a bridging silicon-based protecting group and attaching a suitable side chain. Novel polycyclic fused ring compounds and intermediate compounds are also described.
The present invention provides processes for the production of docetaxel. Docetaxel is produced by protecting the C(7) and the C(10) hydroxy groups of 10-DAB with a bridging silicon-based protecting group. The resulting 7,10-protected 10-DAB derivative is then derivatized and deprotected to form docetaxel.
The present invention provides processes for the production of paclitaxel. Paclitaxel is produced by protecting the C(7) and the C(10) hydroxy groups of 10-DAB with a bridging silicon-based protecting group. The resulting 7,10-protected 10-DAB derivative is then derivatized and deprotected to form paclitaxel.
