The use of t-butyl acrylate as a Michael acceptor led to increase in stereoselectivity as well as chemical yield of the desired product compared to the reported procedure; stereoselectivity: trans/cis=6.5:1, isolated yield of trans isomer: 66%. See Ref. 12c.

note
-
The product was obtained as a separable mixture of diastereoisomers in a ratio of 5:1 and the desired stereoisomer was used for the next reaction. Their stereochemical assignments were unambiguously established by the NOE experiments.
