The main drawback of these methods is probably that a multi-step sequence is generally required, including addition of a sulfur nucleophile and protection/deprotection of amino and thiol groups. 6 A few other methods are limited by less accessible starting materials such as thiiranes, 7 aziridines, 8 or 2-thiazolidinones. 9 Thus, developing a convenient ...
