A study of the semantic characteristics of the modal auxiliaries may and might in Scots
… from Standard English. The use of modal auxiliaries in Present-Day Scots seems to be different from Present-Day Standard English. In this paper the semantics of MAY and MIGHT in Scots are studied. Several studies of Scots, for instance Miller (2003) and Kirk (1987), show that the use of …

A new cyclohexyl-based chiral auxiliary: application in the total synthesis of (+)-linalool oxide
Seven different racemic cyclohexyl-based chiral auxiliaries (2.4-2.10) were synthesised in moderate to good yields (38-85%) by nucleophilic opening of cyclohexene oxide using carbanions. The racemic cyclohexyl-based chiral auxiliaries were coupled with the 6-methyl-2- methylenehept-5-enoyl chloride …
