T1 - Synthesis of n-carbobenzoxy-n, n-acetals

AB - A series of N-carbobenzoxy-N, N-acetals have been synthesized by the reaction of aromatic aldehydes or certain aliphatic aldehydes with benzyl carbamate and morpholine. The N, N-acetals can be converted into N-carbobenzoxy-N, S-acetals with benzyl thiol.

T1 - Synthesis of N -acyl- N, O -acetals mediated by titanium ethoxide

T1 - Enantiomerically pure acetals in organic synthesis. 1. Chromatographic separability of furanoside and pyranoside acetals derived from α-hydroxy esters

Synthesis of acetals - Organic Chemistry Portal

N-Acyl-N,O-acetals are present in a number of bioactive natural products, and this unusual functional group can act as a synthetic precursor to unstable reactive N-acylimines. In this paper, a variety of N-acyl-O-ethyl-N,O-acetals was concisely prepared under mild conditions mediated by titanium ethoxide (Ti(OEt)4). The method also offers a new strategy to make other O-alkyl-N,O-acetals. Furthermore, this strategy was extended to the synthesis of an analogue of the natural product turtschamide.

N2 - Two new ferrocene acetals were synthesized from a chiral diol in toluene and characterized by a range of spectroscopic techniques. The biological activities of the products were evaluated by using the breast adenocarcinoma cell lines T47D, MCF7, ZR-75-1, MD-MB-468, and MD-MB-231. In comparison with tamoxifen, the ferrocene acetals showed moderate anticancer activity in vitro for the T47D and MCF7 cell lines.

T1 - Synthesis and characterization of ferrocene acetals and evaluation of their antineoplastic properties by using breast cancer cell lines in vitro

N2 - A general chromatographic separation of diastereomeric furanoside and pyranoside acetals derived from α-hydroxy esters is described. Application of this separation methodology is made to rapid syntheses of the diastereomers of (S)-methyl lactyl 4-deoxy-β-erythro-pentopyranoside.
