The high facioselectivity in the epoxidation of 4-deoxypentenosides (4-DPs) by dimethyldioxirane (DMDO) correlates with a stereoelectronic bias in the 4-DPs' ground-state conformations, as elucidated by polarized-pi frontier molecular orbital (PPFMO) analysis.
二甲基二氧杂环丙烷(DMDO)对4-脱氧戊烯糖苷(4-DP)进行环氧化反应时表现出的高立体选择性,与4-DP基态构象中的立体电子偏向相关,这一点已通过极化π前沿分子轨道(PPFMO)分析得以阐明。
