Abstract
Metalation of 2-methyl-2-thiazoline (1) using n-butyllithium at low temperature furnishes a nucleophilic thiazoline anion which may be alkylated to n-(alkylmethy1) thiazolines (2). This process may be repeated to produce dialkylated (5 and 9) and trialkylated thiazolines 14. Reduction of the C= N link was readily accomplished using aluminum amalgam in wet ether affording the thiazolidines 3, 6, and 15, respectively. Release of the aldehydes 4, 7, 10, ...
