An efficient synthesis of the C(1)-C(9) fragment of fludelone has been developed. The key step is a tandem silylformylation-crotylsilylation/ Tamao oxidation sequence that establishes the C(5) ketone, the C(6), C(7), and C(8) stereocenters, and the C(9) alkene in a single operation from a readily accessed starting material. The stereochemical outcome at C(6) depends critically on the development of an aprotic Tamao oxidation, which leads to a reversal in the intrinsic diastereoselectivity observed using standard Tamao oxidation conditions.

A novel efficient procedure has been developed for the preparation of acylals in high yields by reaction of the corresponding aldehydes with acetic anhydride in the presence of Al(HSO4)3 as catalyst under mild (room temperature) solvent-free conditions.
PHOTOCHEMISTRY OF BIS(2-METHYL-1-PROPENYL)ETHER AND 2,2,4,4-TETRAMETHYL-6-OXABICYCLOHEXAN-3-ONE: ON THE SEARCH FOR THE OXYDI-?-METHANE REARRANGEMENT

?,?*-Excitation of bis(2-methyl-1-propenyl)ether leads to products derived from a vinyl-vinyloxy radical pair; photochemical decarbonylation (n,?*) of the title ketone provides an entry into the diradical manifold of the oxydi-?-methane rearrangement.
