of the geometry of the allyl halide because of fast E/Z isomerization of
allylchromium species; see: (c) Hiyama, T.; Okude, Y.; Kimura, K.;
Nozaki, H. Bull. Chem. Soc. Jpn. 1982, 55, 561. (d) Hiyama, T.; Kimura,

(16) In the synthetic studies of uprolide D, Marshall et al. noticed that
the intramolecular NHK macrocyclization conformed to anti-Felkin−
Anh model while the intermolecular system was controlled by Felkin−
Anh arrangement; see ref 7b.

(18) The conversion of α-methylene-δ-lactone of crassin acetate to its
γ-lactone was previously reported by Marshall et al. through a 3-step
sequence: Michael addition of PhSH to α-methylene-δ-lactone (PhSH,
Et3N), saponification (KOH, H2O, reflux for 1 h), and oxidative
elimination of the PhS- group (NaIO4); see: Marshall, J. A.; Karas, L. J.;
Coghlan, M. J. J. Org. Chem. 1982, 47, 699.
