Rhizoxin D (2) was synthesized from four subunits, A, B, C, and D representing C3-C9, C10-C13, C14-C19, and C20-C27, respectively. Subunit A was prepared by cyclization of iodo acetal 21, which set the configuration at C5 of 2 through a stereoselecti

An asymmetric synthesis of the C3C13 segment of rhizoxin is described in which the relative stereochemistry of C7 and C8 is established through a chelation-controlled allylation followed by Mitsunobu inversion, and the pyran ring is constructed by

Ortho-lithiation-alkylation of tertiary benzamide provides a series of 2-substituted chiral benzamides 3a-g. Birch reduction of 3a-j followed by alkylation of the resulting chiral amide enolate with MeI at −78°C gives 1,6-dialkyl-1,4-cyclohexadien

4-Carbomethoxy-4-vinyl-2,5-cyclohexadien-1-ones 6a and 6b were prepared from methyl benzoate and methyl 2-methoxybenzoate in 45% overall yields. Irradiation of 6a in benzene solution at 366 nm gave 2-carbometboxybicyclo- [3 2,3,4 .2 6,7 ]-2,6-octadie

1,1,1-Trifluoroethyl esters of ω-hydroxycarboxylic acids were prepared and their conversion to macrocyclic lactones, including ricinelaidic lactone, was studied in the presence of catalytic quantities of tin(IV) reagents; a mechanism involving excha
