Synthesis of Two 2-(Oxoalkyl)-3-methyl-2-cyclopentenones
Reported here are the preparations of 2-(2-oxopropyl)-3-methyl-2-cyclopentenone and the 2,2-dimethyl-1,3-propanediol ketal of 2-(3-oxobutyl)-3-methyl-2-cyclopentenone.A reagent for the convenient preparation of such cyclic ketals is described.

A CONVENIENT PROCEDURE FOR THE REGIOSELECTIVE MONOPROTECTION OF 1,n-DIOLS
A method is described for regioselective monoprotection of 1,n-diols.The new process depends on regioselective cleavage of orthoester, which is prepared in situ from 1,n-diols and trialkylorthoesters.The produced mono-acetal is useful in subsequent steps as a normal acetal type protecting group.
