摘要:The present invention relates to a process for the deprotection of protected amine compounds, wherein the protected amine compound is contacted with an electrophilic oxidating agent that is optionally formed in situ, said electrophilic oxidating agent being selected from the group of I 2 , Br 2 , Cl 2 and compounds comprising a halogen atom having a formal oxidation state of 1+, 3+, 5+ or 7+, provided that the electrophilic oxidating agent is not iodobenzene diacetate. The process can be conveniently employed in the synthesis of 1,3-amino alcohols, β-amino acids and heterocyclic compounds, in particular β-amino acids.

摘要:Reagents particularly useful for the preparation of Alpha Beta -unsaturated aldehydes are provided herein, which reagents consist of compounds of the general formula: WHEREIN R1 is a lower alkyl group, R2 is a member selected from the group consisting of R1O, a lower alkyl group, an aralkyl group of seven to eight carbon atoms and an aryl group of six to seven carbon atoms, R3 is a member selected from the group consisting of an acyclic or cyclic alkyl group of one to six carbon atoms and an aryl group of six to seven carbon atoms, and R4 is a member selected from the group consisting of a hydrogen atom, a lower alkyl group, an aralkyl group of seven to eight carbon atoms, and a halogen atom. These compounds react with carbonyl compounds to form unsaturated aldehydes and are especially useful in the synthesis of various pharmaceutical compounds such as various steroids, vitamin A, vitamin D, etc.
