In order to understand when the orientation of the first cleavage plane is fixed along the animal-vegetal axis in starfish eggs, the behavior of the sperm aster was examined by indirect immunofluorescence staining. After duplication, the sperm aster organizes the mitotic apparatus for first cleavage perpendicular to the cleavage plane. The sperm aster… (More)
The insertion reaction of isocyanide into a C-S bond of dithioacetals is catalyzed by GaCl3 or TiCl4 to afford thioimidates containing an alpha-alkylthio group. Balanced thiophilicity of these Lewis acids is critical for efficient catalysis.
The Brønsted acid catalyzed formal insertion of an isocyanide into a C-O bond of an acetal is described. A diverse array of acyclic and cyclic acetals can be applied to the catalytic insertion to form alpha-alkoxy imidates. Functional groups, such as nitro, cyano, halogen, ester, and alkoxy groups, are tolerant to the reaction conditions employed. The… (More)
