A new synthesis of the 20S proteasome inhibitor clasto-lactacystin beta-lactone is described. Our route to this important natural product involves the partial reduction of an electron deficient pyrrole as a key step. By judicious choice of enolate co

The Birch reduction has been applied to electron-deficient pyrroles substituted with a chiral auxiliary at the C-2 position. Using either 8-phenylmenthol or trans -2-(α-cumyl)cyclohexanol (TCC) as auxiliaries, high levels of stereoselectivity were o

The Birch reduction of electron-deficient 3-substituted pyrroles is described. Use of a reductive alkylation procedure involving sodium metal in liquid ammonia gave good yields of 4-alkyl-2-pyrrolines. The identity of these products was proven by an

The Birch reduction of both pyrroles and furans can be quenched with an aldehyde electrophile, thus constituting a reductive aldol reaction. Although the reaction was not stereoselective, the pyrrolines derived from reduction of pyrroles could be oxi
