概要

• 論文の詳細を見る

• The reaction of 2-imino-1,2-diphenylethanone with sodium in ether and subsequent addition of carbon disulfide or ethyl chloroformate resulted in the formation of 3,4,5-trisubstituted 4-oxazoline-2-thiones and 2-ones, respectively. 1,4-Oxazonines and 1,4-oxazocines were also synthesised from the reaction of 2-imino-1,2-diphenylethanone with sodium in THF followed by addition of dihaloalkanes.
