- 中文摘要: The addition of iodine azide to chiral conjugated N-enoyl-sultam or .alpha.,.beta.-unsaturated N-acyloxazolidinones generated two asymmetric centers at C(.alpha.) and C(.beta.) with high .pi.-face differentiation and regioselectivity. The diastereomerically pure product was easily obtained by crystallization with purity up to 94% de. The structure of 2a was determined by X-ray diffraction analysis which also indicated that B and 4 are reactive conformations.
