Asymmetric synthesis of a fully protected ent-actinoidinic acid

(equation presented) The asymmetric synthesis of a fully protected ent-actinoidinic acid derivative 14 is described. As key steps, an enantioselective deprotonation of an arenetricarbonylchromium(0) complex and a diastereoselective Suzuki coupling were ap

Protection and deprotection of acetals by using MoO3/SiO 2

Acetalization of aldehydes using a new silica-supported molybdenum(VI) oxide (20%) catalyst has been explored. Additionally, facile deprotection strategy for the acetals is reported including the results from the replacement of solvent studies. The protocol achieved the protection O,O-acetals in excellent yield within a few hours under neutral conditions and also deprotection of aromatic O,O-acetals in excellent yields was achieved within a few minutes in aqueous acetone.

Regioselective Reductive Electrophilic Substitution of Derivatives of 3,4,5-Trimethoxybenzaldehyde

The behavior of several protected derivatives of 3,4,5-trimethoxybenzaldehyde has been investigated under conditions of electron transfer from alkali metals in aprotic solvents.The 4-methoxy group can be regioselectively removed in good to high yield under such conditions, and an appropriate choice of the protecting group, metal, and solvent allows its substitution with a variety of electrophiles. 3,4,5-Trimethoxybenzaldehyde dimethyl acetal, 1, is the starting material of choice for a new general synthetic approach to several polysubstituted resorcinol dimethyl ethers.Investigation of the mechanism of demethoxymetylation, with the aid of labeling experiments, showed that reductive demethoxylation is strongly influenced by the nature of the aldehyde protective group employed.
