In this work we have explored the structure directing effect of two of the diastereoisomers of the chiral cation 2-hydroxymethyl-1-benzyl-1-methylpyrrolidinium (bmpm) in aluminosilicate preparations using tetramethylammonium (TMA) as a co-SDA. The pure SS-bmpm isomer, an equimolar mixture of the RS and SS-bmpm isomers and an enriched mixture in the RS isomer (∼77%) were tested in these preparations...
