Zinc or a chromium(II) source with 3-(bromomethyl)furan-2(5H)-one (3) and an aldehyde gives β-(hydroxymethylaryl/alkyl)-α-methylene-γ-butyrolactones 5 in good yields and high diastereoselectivities. The methodology is demonstrated in concise syntheses of (±)-hydroxymatairesinol (8) and (±)-methylenolactocin (10) by subsequent arylboronate conjugate addition and translactonization

In this study, we investigated the effect of three synthetic alpha-methylene-gamma-butyrolactones (MBL) on viability of 10 human tumor cell lines and found that these lactones were highly cytotoxic against leukemia cells. Studies performed on HL-60 cells indicate that MBL induce

Tuliposides, the glucose esters of 4-hydroxy-2-methylenebutanoate and 3,4-dihydroxy-2-methylenebutanoate, are major secondary metabolites in tulip (Tulipa gesneriana). Their lactonized aglycons, tulipalins, function as defensive chemicals due to their biological activities. We recently found that tuliposide-converting enzyme (TCE) purified from tulip bulbs

[reaction: see text] Olefin cross-metathesis between alpha-methylene-gamma-butyrolactone and terminal olefins is described. Moderate to excellent yields of alpha-alkylidene-gamma-butyrolactones were obtained with high E-stereoselectivity in the presence of low catalyst loading in refluxing CH2Cl2. In addition, the use of various additives

Fatty acid synthase (FAS)-catalyzed de novo fatty acid biosynthesis, an anabolic energy-storage pathway largely considered of minor importance in humans, actively contributes to the cancer phenotype by virtue of its ability to specifically regulate the expression and activity of Her-2/neu
