                                The Z-selective intramolecular Horner-Wadsworth-Emmons reaction of the substrates 7-12 (RO)(2)P(O)CHR'CO(2)Et (R' = (CH(2))(n)CHO) (R = Ph or o-tBuC(6)H(4)) gives the 13-18-membered cyclic alkenes selectively (up to Z:E = 97:3) in good yields using NaH in THF under high dilution conditions.
