The totalsynthesis of majusculamide D (MJS-D) is described, a lipopentapeptide originally isolated from Lyngbya majuscula and reisolated from a Moorea sp. MJS-D possesses selective and potent cancer cell toxicity. A scalable and convergent strategy with a minimal number of purifications produced significant quantities of MJM-D for in vivo evaluations. The absoluteconfiguration of the 1,3-dimethyl-octanamide
medicinal agents and bioactive alkaloids. Herein we report a broadly applicable synthesis of enantioenriched NH lactams through a one-pot asymmetric reductive amination/cyclization sequence of easily available keto acids/esters. Such cascade processes alleviate the demand for protecting group manipulations as well as intermediate purification. This strategy is capable of constructing enantioenriched lactams

enantioselective C(sp3)-H functionalization reactions are still highly desirable. In particular, the ability to use attractive noncovalent interactions for rate acceleration and enantiocontrol would significantly expand the current arsenal for asymmetric metal catalysis. Herein, we report the development of a highly enantioselective Ir(III)-catalyzed intramolecular C(sp3)-H amidation reaction of dioxazolone
尽管在过去十年中取得了显着进展,但在对映选择性 C(sp3)-H 官能化反应中手性催化剂的新设计策略仍然是非常需要的。特别是,使用有吸引力的非共价相互作用进行速率加速和对映控制的能力将显着扩展不对称金属催化的当前武器库。在此,我们报告了高对映选择性 Ir(III) 催化的二恶唑酮底物的分子内 C(sp3)-H 酰胺化反应的开发,该反应用于使用新设计的基于 α-氨基酸的手性配体合成光学富集的 γ-内酰胺。这种 Ir 催化的反应在非常温和的条件下以优异的效率进行,并对活化和未活化的烷基 C(sp3)-H 键具有出色的对映选择性。它为γ-烷基γ-内酰胺的不对称合成提供了第一条通用路线。发现水是一种独特的共溶剂,可在 γ-芳基内酰胺生产中实现出色的对映选择性。机理研究表明,配体在 Ir 中心周围形成了一个明确的凹槽型手性袋。该口袋的疏水作用允许在极性或水性介质中轻松立体控制底物结合。这种新的 Ir
