Rca. Isaacs et al., SYNTHESIS OF AN ENANTIOMERICALLY PURE INTERMEDIATE CONTAINING THE CD SUBSTRUCTURE OF TAXOL, Journal of organic chemistry, 58(15), 1993, pp. 3938-3941
A straightforward conversion of the (R)-(-)-Hajos-Parrish ketone 5 to
oxetane 13 is reported. It is anticipated that intermediates related t
o this compound could be useful for the total synthesis of taxol.
