DABCO-catalyzed reaction of 3-methoxy-2-nitrobenzaldehyde with methyl vinyl ketone (MVK) affords a mixture of products, comprising the 'normal' Baylis-Hillman adduct, theMVKdimer and a pair of diastereomeric bis-(MVK)Baylis-Hillman adducts. 1H NMRspectroscopy-based kinetic studies have provided clear insights into the competing pathways and product distribution in this complex reaction.

This paper describes an unexpected and novel nucleophilic phosphine-catalyzed annulation of ethyl (arylimino)acetates to give polysubstituted oxoimidazolidine derivatives in moderate to good yields from simple and easily available starting materials under
1,3,5-triaza-7-phosphaadamantane (PTA): A practical and versatile nucleophilic phosphine organocatalyst
Tang, Xiaofang,Zhang, Bo,He, Zhengrong,Gao, Ruili,He, Zhengjie
, p. 2007 - 2017 (2008/09/18)
In this paper, the air-stable and readily available 1,3,5-triaza-7- phosphaadmantane (PTA) is reported as a practical and versatile nucleophilic phosphine organocatalyst. Under the mediation of 15-30 mol% of PTA, various electrophiles like aldehydes and i
