    cyclisation process on a chiral iodo acetylenic ester. Chiral iodohydrins may be formed by regioselective opening of a chiral epoxy ester, prepared by Sharpless epoxidation. C-2 opening is achieved with TMSCl/Nal and C-3 attack with Mgl2. Subsequent esterification of the 2-iodo compound by reaction with substituted propynoyl triflates gives the key lodo acetylenic esters. This route is highly adaptable to the

    with visible light of S-alkoxycarbonyl xanthates derived from various alcohols gives rise to alkoxycarbonyl radicals with bifurcate reactivity: loss of carbon dioxide leads to deoxygenated derivatives (i.e. alkyl xanthates) whereas intramolecular addition to a suitably located double bond produces lactones; these new reactions were applied to the total synthesis of (±)-cinnamolide and (±)-methylenolactocin

    A facile route for the construction of β-carboxy-α-methylene-γ-lactone unit is described using retro Diels-Alder reaction as the key step. Using this protocol, total synthesis of (±)-methylenolactocin and (±)-protolichesterinic acid has been achieved.

    enantiomers of three biologically relevant paraconic acids—MB‐3, methylenolactocin, and C75—were obtained with enantioselectivities up to 99% by kinetic enzymatic resolutions. Good enantiomeric excesses were obtained for MB‐3 and methylenolactocin, using α‐chymotrypsin and aminoacylase as enantiocomplementary enzymes, while C75 was resolved with aminoacylase. They all were evaluated for their antiproliferative
    通过动力学酶拆分,获得了三种生物学上相关的对锥酸(MB-3,甲基内酯和C75)的两种对映体,其对映体选择性高达99%。使用α-胰凝乳蛋白酶酰酶作为对映体互补酶,MB-3和甲基内酯都获得了良好的对映体过量,而C75则用酰酶进行拆分。对它们的抗增殖,抗菌和抗真菌活性进行了评估,显示出弱的作用,并且在每种情况下对映体之间几乎没有区别。在高浓度(16–64 µg / mL)下,(–)‐ C75可以作为革兰氏阳性菌的抗菌剂。手性27:239–246,2015。©2015 Wiley Periodicals,Inc.
