l‐Menthol was used as a chiral auxiliary for the efficient and simple synthesis of a diastereomerically pure phosphonous acid‐borane monoester monoamide. This compound was used for the synthesis of various enantiomerically enriched phosphinous acid‐borane amides and secondary or tertiary phosphine‐boranes. The latter were obtained through a sequential reductive‐cleavage/alkylation process.
