Mp. Sibi et al., ENANTIOSELECTIVE INTERMOLECULAR FREE-RADICAL CONJUGATE ADDITIONS - APPLICATION OF A PYRAZOLE TEMPLATE, Tetrahedron letters, 38(34), 1997, pp. 5955-5958
An achiral pyrazole template has been evaluated in enantioselective co
njugate radical additions. The enantioselectivity using the pyrazole t
emplate is inferior to those obtained from an oxazolidinone template.
The two templates give products of opposite configuration using the sa
me chiral Lewis acid. (C) 1997 Elsevier Science Ltd.
