“…Since pioneering works reported in 2004 by Terada [63] and Akiyama [64], chiral phosphoric acids have rapidly emerged as a new potent class of Brønsted acid catalysts with remarkable synthetic power owing to its continuous application in the development of new organocatalytic methodologies and resulting in a significant expansion of this field [65] (Fig XII.5). Proof of this substantial progress is the employment of such privileged class of Brønsted acids in the total syntheses of significant compounds as, for instance: ()-arboricine A [66], (S)-anabasine [67], monastrol [68], ()-zampanolide [69], (+)-galipinine [70,71], (+)-cuspareine [70], ()-angusturine [70,72], and torcetrapib [73] (Fig XII.6).…”
