SYNTHESIS OF THE C(3)-C(15) SEGMENT OF RUTAMYCIN-B VIA A C(8)-C(9) FRAGMENT ASSEMBLY ALDOL REACTION - METAL DEPENDENCE OF THE ALDEHYDE AND ENOLATE DIASTEREOFACIAL SELECTIVITIES
Dj. Gustin et al., SYNTHESIS OF THE C(3)-C(15) SEGMENT OF RUTAMYCIN-B VIA A C(8)-C(9) FRAGMENT ASSEMBLY ALDOL REACTION - METAL DEPENDENCE OF THE ALDEHYDE AND ENOLATE DIASTEREOFACIAL SELECTIVITIES, Tetrahedron letters, 36(20), 1995, pp. 3447-3450
The diastereofacial selectivities of aldehyde 2b and ketone 3 are meta
l dependent, and their fragment assembly aldol coupling is a matched d
ouble asymmetric reaction when a chlorortitanium enolate is used.
