摘要:
4-Acetyl-2-alkoxy-7,7-dimethyl-3-oxabicyclo[4.1.0]heptanes are new chemical compounds useful as intermediates for certain pyrethroid esters. They are prepared by ozonolysis of 4-hydroxy-2-carene and reduction of the product formed.
摘要:
A new synthesis of key prostaglandin precursors and intermediates employed in their preparation. The novel synthetic sequence of this invention is shorter and more efficient than those previously employed to prepare to key intermediate.
摘要:
Novel compounds prepared by microbial transformation using novel mutants to selectively degrade steroids with or without 17-alkyl side chains of from 2 to 10 carbon atoms, inclusive. These compounds can be used as intermediates to make useful steroids.
