supporting information; experimental part, p. 6031 - 6033 (2010/11/21)
A solvent-free method of generating monoacylaminals by heating the amide and aminal starting materials in the presence of one another has been developed. Yields were generally between 45% and 65% with the monoacylaminal being isolated, needing no further purification after drying under high vacuum.
Novel synthesis of α-acetylstyrylphosphonates

, p. 705 - 713 (2007/10/02)
α-Acetylstyrylphosphonates were conveniently synthesized from 2-oxopropylphosphonates and substituted (dimorpholinomethyl)-benzenes (animals). 4-Benzylidenemorpholinium carboxylates, generated from animals by the action of α-halo acids, reacted with the phosphonates to give the products by elimination of the amine. The yields were influenced by the nature of substituents and their position in the phenyl ring and could be improved by adjustment of the acidities of the reacted acids. α-Acetylstyrylphosphonates containing various substituents on every position (at the 2-, 3-, or 4-position) in the phenyl ring were obtained generally in excellent yields using monochloroacetic acid.
