A Phosphine-Mediated Construction of 1,4-Oxazepines and 1,3-Oxazines
摘要:
A simple and efficient method for constructing 1,4-oxazepines and 1,3-oxazines was developed with use of a phosphine-mediated tandem reaction of ynones with 2-azido alcohols. The method offers a promising route to synthetically useful as well as biologically active heterocycles under mild conditions and may be exploited for the preparation of interesting chiral ligands.
biocatalysts for the synthesis of β‐substituted alcohols based on their epoxide ring‐opening activity with a number of small anionic nucleophiles. In an attempt to further broaden the scope of substrates accepted by these enzymes, a panel of 22 HHDHs was investigated in the conversion of aliphatic and aromatic vicinally di‐substituted trans‐epoxides using azide as nucleophile. The majority of these HHDHs
