S. Kii et K. Maruoka, Practical approach for catalytic asymmetric allylation of aldehydes with achiral bidentate titanium(IV) complex, TETRAHEDR L, 42(10), 2001, pp. 1935-1939
A new, chiral bidentate Ti(IV) complex of type 1 was successfully designed
and can be utilized for simultaneous coordination to aldehyde carbonyls, th
ereby allowing the precise enantioface discrimination of such carbonyls for
a new catalytic, practical enantioselective allylation of aldehydes with a
llyltributyltin. (C) 2001 Elsevier Science Ltd. All rights reserved.
