Abstract

A process is provided for preparing dioxolenone derivatives of the structure ##STR1## wherein R is alkyl or aryl and R.sub.3 is CO.sub.2 R.sub.2 (where R.sub.2 is alkyl or arylalkyl such as benzyl, diphenylmethyl or para-methoxybenzyl). Intermediates produced in the above process are also provided as well as a method for preparing squalene synthetase inhibitors employing such intermediates.
