Abstract

Summary Alkane- (or arene)-thiols or thiolates add smoothly to esters or amides of l-methylpyridinium-3,5- dicarboxylic acid salts ; on treatment of these adducts with activated acid-derivatives, thioesters are formed in excel- lent yields. ... GROUP-TRANSFER reactions play an important role in bio- chemical systems. A special group transfer, namely NAD(P)H mediated 'hydride' transfer,'? makes use of the dihydropyridine-pyridinium salt link. In principle, this ...
