(±)-6-Methyl-6-azabicyclo[3.2.1]octan-3-one (1c) was prepared in three steps from 6-oxabicyclo[3.2.1]oct-3-en-7-one, and stereoselective reduction of (1c) provided (±)-6-methyl-6-azabicyclo[3.2.1]octan-3α-ol (1a); adaptation of the sequence provided the first synthesis of (+)- and (–)-(1a).

The synthesis and antimuscarinic properties of 6-methyl-6-azabicyclo[3.2.1]octan-3 alpha-ol 2,2-diphenylpropionate (1, azaprophen) are described. Azaprophen is 50 times more potent than atropine as an antimuscarinicagent as measured by the inhibition of acetylcholine-induced contraction of guinea pig ileum and is more than 1000 times better than atropine in its ability to block alpha-amylase release
