An expedient access to optically active spiro-[butyrolactone-pyrrolidine] was successfully developed via an unprecedented Cu(I)-catalyzed exo-selective 1,3-DC of azomethine ylides with α-methylene-γ-butyrolactone, which exhibited high diastereoselectivity (>98 : 2), excellent enantioselectivity (96->99% ee) and a broad substrate scope under mild conditions.

Upon exposure of acrylic ester 1 to alcohols 2a-i in the presence of a cyclometalated iridium catalyst modified by (-)-TMBTP, catalytic C-C coupling occurs, providing enantiomerically enriched 5-substituted α-exo-methylene γ-butyrolactones 3a-i. Bromination of the methylene butyrolactone products followed by zinc-mediated

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

[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

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
