Abstract: A possible biosynthetic pathway of bis-alpha-substituent pyrrolidine alkaloids was proposed. Based on the proposed biosynthetic pathway, six pyrrolozoxazine alkaloids and one N-alkyl-5-hydroxymethyl-pyr-role-2-carbaldehyde alkaloid were synthesized. In a mixture of acetic acid and triethylamine, condensation of n-fructose and D-amino acids produced pyrrolozoxazine alkaloids. Replacing D-amino acids with tyramine can afford pyrrolezanthine a N-alkyl-5-hydroxymethyl-pyr-role-2-carbaldehyde alkaloid. (C) 2016 Published by Elsevier Ltd.
