Its full name describes a spiroacetal framework carrying two stereocentres of R,R configuration together with two positively charged ammonium centres, each balanced by a tetrafluoroborate anion.

Four 4-methylbenzyl groups, together with the two benzyl groups on the spiro skeleton, assemble a firmly defined steric environment, so a substrate can only approach comfortably through one particular orientation and the reaction delivers product with high enantiomeric excess.
