Several new benzoate ester derivatives of ethyl a-hydroxymethylacrylate were synthesized using phase transfer catalysis and found to display unexpectedly rapid photopolymerization; i.e., from 2 to 8 times faster than MMA. New derivatives described here include the 4fluoro-, 4-trifluoromethyl-, 4-met
A series of N-formyl-O-acyl-β-phenylserine derivatives 1b -7b were prepared by the interaction of N-acylβ-phenylserine ethyl esters 1a-7a with formic acid in presence of 1.5% HF. One-pot acyl group N→O migration followed N-formylation under elaborated reaction conditions. Results and Discussion
