N‐sulfonylimine from readily available α‐amidosulfones and as a chiral nucleophile to initiate the enantioselective aza‐Morita–Baylis–Hillman (aza‐MBH) reaction. α‐Methylene‐β‐amino‐β‐alkyl carbonyl compounds, difficultly accessible previously, can now be synthesized in excellent yields and enantioselectivities.
双功能催化剂6'-脱氧-6'-酰基氨基-β-异cup啶(1)既可以作为触发从现成的α-酰胺砜中原位生成N-磺酰亚胺的碱,也可以作为手性亲核试剂来引发对映选择性氮杂-Morita-Baylis-Hillman(Aza-MBH)反应。以前难以获得的α-亚甲基-β-氨基-β-烷基羰基化合物现在可以以高收率和对映选择性合成。
