Synthesis of Baylis–Hillman-Derived Phosphonated 3-(Benzylaminomethyl)coumarins
摘要:
Treatment of Baylis-Hillman-derived 3-(chloromethyl)coumarins with benzylamine has afforded benzylamino derivatives, sequential chloroacetylation and Michaelis-Arbuzov phosphonation of which have provided access to a series of phosphonate esters as potential HIV-1 protease inhibitors.

Abstract Reaction of various 3‐substituted coumarins with nitrogen and carbon nucleophiles appears to involve, in all cases examined, exclusive, direct substitution at the exocyclic C‐1′ electrophilic center.

Abstract A general, chemoselective approach to 3-substituted coumarins via Baylis–Hillman reactions of O-benzylated salicylaldehyde precursors has been demonstrated. Competitive cyclization to chromene derivatives is inhibited by conjugate addition of benzylamine or piperidine to the α,β-unsaturated ester intermediates.
