A straightforward and reliable method for the regioselective synthesis of steroidal 1,4-disubstituted triazoles and 1,5-disubstituted tetrazoles via copper(I)-catalyzed cycloadditions is reported. Heterocycle moieties were efficiently introduced onto

A simple one-pot Prins–Ritter route was developed for the synthesis of 16-acylamino-17a-hydroxy- d -homoestrone 3-benzyl and 3-methyl ethers in the 13α-estrone series. The d -secosteroidal δ-alkenyl-aldehydes were allowed to react with different

δ-Alkenyl oximes of 13α-estrone 3-methyl ether undergo intramolecular 1,3-dipolar cycloaddition reactions with BF3•OEt2 as catalyst, furnishing isoxazolidines. The reactions of the 13α- and 13β-estrone oximes with electrophiles lead to cyclic n

The Claisen condensations of 3β-acetoxypregn-5-en-20-one ( 1 ) and 3β-acetoxypregna-5,16-diene ( 7 ) with dimethyl oxalate are known to lead to 3β-hydroxy-21-methoxalylpregn-5-en-20-one ( 2 ) and 3β-hydroxy-21-methoxalylpregna-5,16-dien-20-one (

Cyclic nitrones of estrone 3-methyl or 3-benzyl ether were reacted with phenyl isocyanate or nonsubstituted phenyl isocyanates as reactive CN dipolarophiles, yielding condensed homosteroidal oxadiazolidinones. These dipolar cycloadditions were carrie
