A convenient and stereoselective synthesis of episulfides based on the reaction of readily available S-(β-oxoalkyl) thiophosphate with sodium borohydride and their conversion into alkenes is described.
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

Smooth salen: Ru(CO)–salen complex 1 is an effective catalyst for asymmetric benzylic and allylic CH bond amination using 2‐(trimethylsilyl)ethanesulfonyl azide (SESN3) as the nitrene source. The reaction proceeded with high enantioselectivity and excellent regioselectivity. An ethyl group can be selectively aminated, even in the presence of an n‐propyl group. No migration or isomerization of the
