, p. 1061 - 1067 (1997)
A new method for the preparation of enantiomerically pure N-benzyl nitrones is described. By using either a one-pot reduction-transimination or a one-pot Grignard addition-transimination sequence chiral O-protected α-hydroxynitriles can be converted into chiral aldo- and ketonitrones, respectively.

An efficient approach to access functionalized (2,3-dihydroisoxazol-4-yl) ketones has been developed by reacting nitrones 4 with ynones 7 or terminal ynones 10 in a one-pot fashion. The reaction went through a formal Sc(OTf)3-catalyzed [3 + 2]-cycloaddition process to generate a number of functionalized (2,3-dihydroisoxazol-4-yl) ketones 11aa-11aw, 11ba-11la and 12aa-12ae in moderate to good yields.
