Ra. Bunce et Cr. Harris, ETHYL ISK)-OCTAHYDRO-7A-METHYL-7-OXO-1H-INDENE-1-ACETATE USING TANDEMREACTIONS, Synthetic communications, 26(10), 1996, pp. 1969-1975
The title compound was prepared in 29.5% overall yield using a five-st
ep sequence involving two tandem reactions. The current work supports
the earlier finding that a strong thermodynamic preference exists for
an all-cis relationship across the three contiguous stereocenters at C
(1), C(3a), and C(7a).
