The preparation of 4-methoxy-6-methyl-3-oxidopyrylium ylid from α-deoxykojic acid and its cycloaddition behavior as a 5 carbon dipole or carbonyl ylid with various dipolarophiles is described.

7-dHT synthesis, which we apply in the synthesis of a plausible biosynthetic intermediate to the natural products puberulic and puberulonic acid. We have also tested these new compounds in several biological assays related to human immunodeficiency virus (HIV), hepatitis B virus (HBV) and herpes simplex virus (HSV) in order to gain insight into structure-functional analysis related to antiviral troponoid
Triflic Acid-Mediated Rearrangements of 3-Methoxy-8-oxabicyclo[3.2.1]octa-3,6-dien-2-ones: Synthesis of Methoxytropolones and Furans

because of their known biological activity and established value in the synthesis of α-hydroxytropolones. Upon treatment with triflic acid, a series of 3-methoxy-8-oxabicyclo[3.2.1]octa-3,6-dien-2-ones rearrange rapidly and cleanly to form methoxytropolones. Interestingly, bicycles that are derived from dimethyl acetylenedicarboxylate (R2 = R3 = CO2Me) instead form furans as the major product.
甲氧基托酚酮是用于治疗开发的有用支架,因为其已知的生物活性和在 α-羟基托酚酮合成中的确定价值。用三氟甲磺酸处理后,一系列 3-甲氧基-8-氧杂二环[3.2.1]八-3,6-二烯-2-酮快速而干净地重排,形成甲氧基托酚酮。有趣的是,衍生自乙炔二甲酸二甲酯(R 2 = R 3 = CO 2 Me)的自行车反而形成呋喃作为主要产物。
Catalytic Enantioselective Intermolecular [5 + 2] Dipolar Cycloadditions of a 3-Hydroxy-4-pyrone-Derived Oxidopyrylium Ylide

The first catalyticenantioselective [5 + 2] dipolar cycloaddition of a 3-hydroxy-4-pyrone-derived oxidopyryliumylide is described. These studies leveraged the recently recognized ability of oxidopyrylium dimers to serve as the source of ylide, which was found to be key to increasing yields and achieving enantiomeric excesses up to 99%. General reaction conditions were identified for an array of α
