A possible biosyntheticpathway of bis-α-substituent pyrrolidine alkaloids was proposed. Based on the proposed biosyntheticpathway, six pyrrolozoxazine alkaloids and one N-alkyl-5-hydroxymethyl-pyrrole-2-carbaldehyde alkaloid were synthesized. In a mixture of acetic acid and triethylamine, condensation of d-fructose and d-amino acids produced pyrrolozoxazine alkaloids. Replacing d-amino acids with
