The present invention is directed to a process for the preparation of β-lactams. Generally, an imine is cyclocondensed with a ketene acetal or enolate to form the β-lactam product in a “one pot” synthesis, this...
A taxane having a cyclopentyl ester substituent at C10, a keto substituent at C9, a hydroxy substituent at C2, a 2-thienyl substituent at C3′ and an isopropoxycarbamate substituent at C3′.
A process for the preparation of a composition having the formula: in which a compound having the formula: is treated with a base and a silylating agent.
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...
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...
A process for the preparation of a compound having the formula: the process comprising treating a compound having the formula: with an alkyl metal species or with a Lewis acid in the presence of a tertiary amine base, wherein P2 is...
A process for the preparation of a compound having the formula: ##STR1## in which a compound having the formula: ##STR2## is treated with a base and a silylating agent.
A taxane having a cyclopentyl ester substituent at C10, a keto substituent at C9, a hydroxy substituent at C2, a 2-thienyl substituent at C3′ and an isopropoxycarbamate substituent at C3′.
Processes for the production of polycyclic fused ring compounds
Description:
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...
C(10) ethyl ester and C(10) cyclopropyl ester substituted taxanes
Description:
Taxanes having an ethyl ester or cyclopropyl ester substituent at C(10), a keto substituent at C(9), a hydroxy substituent at C(7), a thienyl substituent at C(3′) and a cyclobutyloxycarbamate or cyclopentyloxycarbamate substituent...
