An unprecedented outcome of the lithium–ammonia reduction of enones: the formation of cyclopropanols

Autor: Cyrille Thominiaux, Didier Desmaële, Christine Miet, Christian Cavé, Jean d'Angelo, Marie-Elise Tran Huu-Dau, Mohammed Nour, Georges Morgant, Françoise Dumas

Publikováno v: Tetrahedron Letters. 43:9649-9652

An unusual process takes place during the lithium–ammonia reduction of a variety of cyclic enones bearing an ester group in the γ-position, furnishing cyclopropanols. The reason for this unprecedented outcome has been attributed to the through-spa

Autor: Loïc René, Loïc Yaouancq, Bernard Badet, Marie-Elise Tran Huu Dau

Publikováno v: The Journal of Organic Chemistry. 67:5408-5411

A general method giving access to protected alpha-alkyl amino glycines (A3G) 4 from the previously described precursor alpha-isopropylthioglycine 1 is described. In the presence of N-bromosuccinimide, displacement of the thiol by a large variety of a
