Stanozolol is the generic name of stanozolol in English , German , French , and Japanese and its INN , USAN , USP , BAN , DCF , and JAN , while stanozololum is its name in Latin , stanozololo is its name in Italian and its DCIT , and estanozolol is its name in Spanish . [2] [34] [1] Androstanazole , stanazol , stanazolol , and estanazolol are unofficial synonyms of stanozolol. [2] [1] The drug is also known generically by its former developmental code names NSC-43193 and WIN-14833 . [34]

When ketones are treated with base , enolates can be formed by deprotonation at either α-carbon. The selectivity is determined by both the steric and electronic effects on the α-carbons as well as the precise base used (see figure ""Masked functionality" for regiospecific enolate formation" for an example of this). Enolate formation will be thermodynamically favoured at the most acidic proton which depends on the electronic stabilization of the resulting anion . However, the selectivity can be reversed by sterically hindering the thermodynamic product and therefore kinetically favouring deprotonation at the other α-carbon centre. Traditional methods for regioselective enolate formation use either electronic activating groups (. aldehydes ) or steric blocking groups (. 1,2-ethanedithiol protected ketone).
