    • The stereochemistry of the major isomers 5, 7, 16, and 20 was elucidated by NOESY experiments and in some cases indirectly confirmed by X-ray structure analysis of compounds 10 and 13 (see Supporting Information). Similarly, the syn stereochemistry of aldol 12 was validated by the structure of 13.

    • Unfortunately, all attempts to effect an analogous condensation with phosphonolactone 15 were unsuccessful because of the instability of (Z)-3-iodomethacrolein under the reaction conditions.

    • The spectral data of 27 resemble the corresponding signals of the SNF compounds. For instance, the vinylic proton at C14 is markedly shifted upfield (δ 5.00 in SNF4435 C, 4.93 in SNF4435 D, and 4.41 in 27).
