- A polemic on the work of A. Al-Mourabit et al. (Org. Lett. 2004, 6, 3933-3936) with new data. The tautomers I-IV of the marine metabolite 3-amino-1-(2-aminoimidazol-4-yl)prop-1-ene (1) were previously suggested to have ...
- First synthesis of bi- and tricyclic a,b-unsaturated d-oxacaprolactams from cyclic imines via ring-closing metathesis.
