Abstract:
[reaction: see text] A new stereoselective synthesis of the antifungal and antitumor agents Preussin and 3-epi-Preussin via a Pd-catalyzed carboamination of a protected amino alcohol is described. The key transformation leads to simultaneous formation of the N-C2 bond and the C1'-aryl bond, and allows installation of the aryl group one step from the end of the sequence. This strategy permits the facile construction of a variety of preussin analogues bearing different aromatic groups.

Preparation of Epoxides
Epoxides result from alkene oxidation, which can be achieved by a) air, b) peroxy acids, c) hypochlorous acids, and d) halohydrin cyclization.
Epoxidation with Peroxy Acids
Epoxidation of alkenes via oxidation with peroxy acids involves the conversion of a carbon–carbon double bond to an epoxide using the oxidizing agent meta-chloroperoxybenzoic acid, commonly known as MCPBA. Since the O–O bond of peroxy acids is very weak, the addition of electrophilic oxygen of peroxy acids to...
