摘要

Abstract: The stereochemistry of the head-to-head rearrangement which occurs during biosynthesis of squalene from presqualene pyrophosphate was studied with a ten-carbon model system, N-methyl-4-[(lS, 1'R, 3'R)-[l-3H] chrysanthemyloxy] pyri-dinium iodide, in a nonenzymatic reaction. A head-to-head product,[5-3H]-2, 7-dimethylocta-2, 6-dien-4-ol, is isolated after hydrolysis. The absolute configuration at C (5) was determined by converting ...
